Import Libraries in Jupyter Notebook

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
import seaborn as sns

pandas (imported as pd): Pandas is a powerful library for data manipulation and analysis. It provides data structures like DataFrames and Series that allow you to work with structured data efficiently.
numpy (imported as np): NumPy is a library for numerical computations in Python. It provides support for large, multi-dimensional arrays and matrices, along with mathematical functions to operate on these arrays.
matplotlib.pyplot (imported as plt): Matplotlib is a widely used library for creating static, interactive, and animated visualizations in Python. The pyplot module within Matplotlib provides a MATLAB-like interface for generating plots and charts.
seaborn (imported as sns): Seaborn is built on top of Matplotlib and provides a higher-level interface for creating informative and attractive statistical graphics. It simplifies the process of creating complex visualizations and comes with several built-in themes and color palettes.

Exploring the seaborn Library:

Seaborn is particularly useful for statistical data visualization. It provides a variety of functions to create visually appealing plots with less code compared to using Matplotlib directly. Seaborn’s features include:

High-Level Functions: Seaborn offers functions to create common types of statistical plots such as scatter plots, bar plots, histograms, box plots, etc. These functions often take a DataFrame or Series as input and handle much of the underlying plotting logic automatically.
Enhanced Aesthetics: Seaborn provides a set of built-in themes and color palettes that make your plots more visually appealing by default. This reduces the need for manual customization.
Statistical Estimations: Many Seaborn plots include options for adding statistical estimations to the visualization, such as regression lines on scatter plots or confidence intervals on bar plots.
Categorical Plotting: Seaborn simplifies working with categorical data by providing functions for creating plots that summarize and compare data within different categories.
Overall, Seaborn complements Matplotlib by simplifying the process of creating complex visualizations, making it a popular choice for data analysts and scientists.

Please note that while the code snippet imports the libraries, it doesn’t include any actual code for data manipulation or visualization. You would typically write additional code to load data using Pandas, perform data analysis or transformations using both Pandas and NumPy, and then use Seaborn (and Matplotlib) to create visualizations based on the analyzed data.

Read Csv File

data = pd.read_csv(r"C:\Users\yogesh\Downloads\Airline+Passenger+Satisfaction\airline.csv")

import pandas as pd:

This imports the Pandas library and assigns it the alias pd. This is a common convention to make the code shorter when referring to Pandas functions.

data = pd.read_csv(r”C:\Users\yogesh\Downloads\Airline+Passenger+Satisfaction\airline.csv”): Here’s what each part of this line does:

data:

This is a variable name that you’re using to store the data read from the CSV file. You can choose any variable name you prefer.

pd.read_csv(): This is a Pandas function that reads a CSV file and returns its content as a DataFrame.
r”C:\Users\yogesh\Downloads\Airline+Passenger+Satisfaction\airline.csv”: This is the path to the CSV file that you want to read. The r before the string indicates that it’s a “raw” string, which means backslashes are treated as literal characters and not escape characters. Adjust the path to match the location of your actual “airline.csv” file.
Once the code is executed, the CSV file’s contents will be loaded into the data DataFrame.

print(data.head())

The print(data.head()) command is used to display the first few rows of the DataFrame data. The .head() method in Pandas returns the top rows of a DataFrame, by default the first 5 rows.

The print(data.head()) command is used to display the first few rows of the DataFrame data. The .head() method in Pandas returns the top rows of a DataFrame, by default the first 5 rows.

Display basic info about the dataset

print(data.info())

The information displayed typically includes:
The total number of non-null entries in each column.
The data type of each column (e.g., integer, float, string, datetime, etc.).
The memory usage of the DataFrame.
The index information.
Additional metadata about the DataFrame.

The describe() function

print(data.describe())

When applied to a Pandas DataFrame or Series, the describe() function provides a summary of descriptive statistics for the data. These statistics include measures such as mean, standard deviation, minimum, maximum, and quartiles for numerical data, as well as count and unique values for categorical data.

Isnull Function in Pandas for Data analytics

#Check for missing values
print(data.isnull().sum())

when you run print(data.isnull().sum()), it will print the count of missing values in each column of your DataFrame. In below out put arrival delay have 393 missing values.

fillna function for filling values in Pandas

# Assuming 'data' is your DataFrame
data['Arrival Delay'] = data['Arrival Delay'].fillna(0)

# Print to verify the changes
print(data.isnull().sum())

Fill 0 in missing value in dataframe.

Charting in Python

# Define the categories of columns
categories = ['Ease of Online Booking', 'Check-in Service', 'Online Boarding',
              'Gate Location', 'On-board Service', 'Seat Comfort',
              'Leg Room Service', 'Cleanliness', 'Food and Drink',
              'In-flight Service', 'In-flight Wifi Service', 'In-flight Entertainment']

# Calculate the averages for each category
category_averages = data[categories].mean()

# Create a bar chart
plt.figure(figsize=(10, 6))
category_averages.plot(kind='bar', color='orange')
plt.title('Average Ratings for Flight Experience Categories')
plt.xlabel('Categories')
plt.ylabel('Average Rating')
plt.xticks(rotation=45)
plt.tight_layout()

# Show the chart
plt.show()

Column Categories Definition:

A list called categories is defined, containing the names of different categories that are likely related to the evaluation of a flight experience. These categories might include things like ease of online booking, check-in service, seat comfort, in-flight entertainment, etc.

Calculating Category Averages:

The code assumes the existence of a DataFrame named data, which presumably contains ratings or scores for each of the specified categories. The mean() function is used to calculate the average value for each category based on the ratings provided in the DataFrame.

Creating a Bar Chart:

The code uses the matplotlib library to create a bar chart. It sets the figure size to 10×6 inches with plt.figure(figsize=(10, 6)). Then, it plots the average ratings using the category_averages Series as data, and sets the bars to be colored orange (color=’orange’). The kind parameter is set to ‘bar’ to indicate that a bar chart should be created.

Chart Title and Labels:

Various attributes are set to customize the appearance of the chart. The plt.title() function sets the chart title to ‘Average Ratings for Flight Experience Categories’. The plt.xlabel() and plt.ylabel() functions set the labels for the x-axis and y-axis respectively. The plt.xticks(rotation=45) function rotates the x-axis labels by 45 degrees for better readability.

Adjusting Layout and Displaying:

The plt.tight_layout() function is called to ensure that the plot elements do not overlap. Finally, plt.show() is called to display the generated bar chart.

In summary, this code takes ratings or scores for different flight experience categories from a DataFrame, calculates the average ratings for each category, and then creates and displays a bar chart to visually represent these average ratings. The chart provides insights into which categories of the flight experience are rated more favorably or less favorably on average.

Create a line plot

 #Create a line plot
plt.figure(figsize=(10, 6))
category_averages.plot(kind='line', marker='o', color='blue')
plt.title('Average Ratings for Flight Experience Categories')
plt.xlabel('Categories')
plt.ylabel('Average Rating')
plt.xticks(rotation=45)
plt.tight_layout()

# Show the chart
plt.show()

plt.figure(figsize=(10, 6)): This line creates a new figure (plotting area) with a specified size of 10 inches in width and 6 inches in height. This sets up the canvas on which the plot will be drawn.
category_averages.plot(kind=’line’, marker=’o’, color=’blue’): This line is creating the line plot itself. It’s assumed that category_averages is a DataFrame or a Series containing data for the plot. Here’s what each parameter does:
kind=’line’: Specifies that a line plot should be created.
marker=’o’: Sets circular markers at data points on the line.
color=’blue’: Sets the color of the line and markers to blue.
plt.title(‘Average Ratings for Flight Experience Categories’): This sets the title of the plot to “Average Ratings for Flight Experience Categories”.
plt.xlabel(‘Categories’): This sets the label for the x-axis to “Categories”.
plt.ylabel(‘Average Rating’): This sets the label for the y-axis to “Average Rating”.
plt.xticks(rotation=45): This rotates the x-axis labels by 45 degrees. This is often done to prevent overlapping when labels are long or numerous.
plt.tight_layout(): This function adjusts the spacing between the plot elements to ensure they fit well within the figure area.
plt.show(): This line displays the plot on the screen.

In summary, the code creates a line plot that displays average ratings for different flight experience categories. The categories are labeled on the x-axis, the average ratings are on the y-axis, and each data point is marked with a blue circular marker. The plot has a title and axis labels, and the x-axis labels are rotated for better readability. Finally, the plot is displayed using plt.show().

Create a histogram

#Create a histogram for the "Age" column
plt.figure(figsize=(10, 6))
plt.hist(data['Age'], bins=20, color='skyblue', edgecolor='black')
plt.title('Age Distribution')
plt.xlabel('Age')
plt.ylabel('Frequency')
plt.tight_layout()

# Show the histogram
plt.show()

The plt.figure(figsize=(10, 6)) line sets the dimensions of the plot. The plt.hist() function is used to create the histogram. It takes the ‘Age’ column data from the dataset (data[‘Age’]), divides it into 20 bins, and represents the data using bars in the plot. The bars are colored in sky blue and have black edges. The plt.title() function sets the title of the plot to “Age Distribution,” while plt.xlabel() and plt.ylabel() set the labels for the x-axis and y-axis respectively. The plt.tight_layout() function adjusts the spacing of the plot elements for better layout. Finally, plt.show() is called to display the histogram plot. The histogram provides a visual representation of how the ages are distributed within the dataset, showing the frequency of ages in different bins.

Age Groups to the Dataset:

# Define labels for the age bins
age_labels = ['0-18', '19-30', '31-40', '41-50', '51-60', '61-70', '71+']

# Add a new column with age groups
data['Age Group'] = pd.cut(data['Age'], bins=7, labels=age_labels)

# Display the modified data with age groups
print(data['Age Group'])

age_labels: This is a list of labels representing different age bins or groups. Each label corresponds to a specific age range.
data[‘Age Group’] = pd.cut(data[‘Age’], bins=7, labels=age_labels): This line of code adds a new column called ‘Age Group’ to the DataFrame data.
The pd.cut() function is used to categorize the values in the ‘Age’ column into 7 bins (or age groups) based on the specified labels and number of bins. The resulting categories are assigned the labels from the age_labels list.
print(data[‘Age Group’]): This line prints out the newly created ‘Age Group’ column, displaying the age group label for each row of data.

In summary, the code takes an existing DataFrame with an ‘Age’ column, divides the age values into 7 different age groups, assigns corresponding labels to these groups, and then adds a new ‘Age Group’ column to the DataFrame to store these group labels. This can be useful for segmenting and analyzing data based on different age ranges.

Passenger Distribution by Age Group

age_group_counts = data['Age Group'].value_counts().sort_index()
#Create a bar chart
plt.figure(figsize=(10, 6))
age_group_counts.plot(kind='bar', color='skyblue')
plt.title('Passenger Distribution by Age Group')
plt.xlabel('Age Group')
plt.ylabel('Number of Passengers')
plt.xticks(rotation=0)
plt.tight_layout()

# Show the chart
plt.show()

age_group_counts = data[‘Age Group’].value_counts().sort_index():

This line calculates the count of passengers in each age group using the ‘Age Group’ column of the DataFrame. The .value_counts() function counts the occurrences of each unique value (in this case, the different age group labels), and .sort_index() sorts these counts based on the order of the age labels.

Creating the Bar Chart:

plt.figure(figsize=(10, 6)): This line sets the size of the figure (the plot) to have dimensions of 10 units in width and 6 units in height.
age_group_counts.plot(kind=’bar’, color=’skyblue’):
This line creates a bar plot using the counts calculated in the previous step. Each age group will have a corresponding bar, and the bars will be colored with a sky blue color.
plt.title(‘Passenger Distribution by Age Group’): Sets the title of the plot to ‘Passenger Distribution by Age Group’.
plt.xlabel(‘Age Group’): Sets the label for the x-axis to ‘Age Group’.
plt.ylabel(‘Number of Passengers’): Sets the label for the y-axis to ‘Number of Passengers’.
plt.xticks(rotation=0): Sets the rotation angle of the x-axis labels to 0 degrees, meaning the labels will be displayed horizontally.
plt.tight_layout(): Automatically adjusts the subplot parameters to ensure that all elements of the plot fit within the figure area without overlapping.

Create Pie Chart

gender_counts = data['Gender'].value_counts() customer_type_counts = data['Customer Type'].value_counts() travel_type_counts = data['Type of Travel'].value_counts() class_counts = data['Class'].value_counts()

Here, you’re calculating the count of unique values in the ‘Gender’, ‘Customer Type’, ‘Type of Travel’, and ‘Class’ columns of the DataFrame data and storing them in separate variables.

Creating Subplots:

fig, axes = plt.subplots(2, 2, figsize=(12, 10))

You’re creating a 2×2 grid of subplots (four subplots in total) using the subplots function from the matplotlib.pyplot library. The figsize parameter determines the size of the entire figure.

Pie Chart Creation

axes[0, 0].pie(gender_counts, labels=gender_counts.index, autopct='%1.1f%%', startangle=90)
axes[0, 1].pie(customer_type_counts, labels=customer_type_counts.index, autopct='%1.1f%%', startangle=90)
axes[1, 0].pie(travel_type_counts, labels=travel_type_counts.index, autopct='%1.1f%%', startangle=90)
axes[1, 1].pie(class_counts, labels=class_counts.index, autopct='%1.1f%%', startangle=90)

You’re creating individual pie charts for each categorical variable. For each subplot, you’re using the pie function to create the pie chart. The labels parameter specifies the labels for each slice of the pie chart, the autopct parameter formats the percentage labels on the chart, and startangle determines the angle at which the first slice starts.

Setting Titles:

axes[0, 0].set_title('Gender Distribution')
axes[0, 1].set_title('Customer Type Distribution')
axes[1, 0].set_title('Type of Travel Distribution')
axes[1, 1].set_title('Class Distribution')

Layout Adjustment and Displaying:

plt.tight_layout()
plt.show()

plt.tight_layout() adjusts the spacing between subplots for better visualization. Finally, plt.show() displays the entire figure with the pie charts.

bar chart of satisfaction Mapping

satisfaction_mapping = {
    'Neutral or Dissatisfied': 0,
    'Satisfied': 1
}

In this step, a dictionary named satisfaction_mapping is created. It maps categorical satisfaction values (‘Neutral or Dissatisfied’ and ‘Satisfied’) to numerical values (0 and 1, respectively).

Step 2: Map the Satisfaction Values

data['Satisfaction'] = data['Satisfaction'].map(satisfaction_mapping)

the ‘Satisfaction’ column in the DataFrame named data by applying the mapping defined earlier. This maps the categorical values to their corresponding numerical values in the DataFrame.

Step 3: Calculate Average Satisfaction for Each Class

class_satisfaction = data.groupby('Class')['Satisfaction'].mean()

This line groups the data in the DataFrame by the ‘Class’ column and calculates the mean (average) of the ‘Satisfaction’ values for each class. The result is stored in the class_satisfaction Series.

Step 4: Create a Bar Chart

plt.figure(figsize=(10, 6))
class_satisfaction.plot(kind='bar', color='skyblue')

In this step, a bar chart is created using the matplotlib library. The plt.figure(figsize=(10, 6)) sets the size of the figure, and class_satisfaction.plot(kind=’bar’, color=’skyblue’) plots the average satisfaction values for each class as bars, using the color ‘skyblue’.

Step 5: Add Chart Details

plt.title('Average Satisfaction by Class')
plt.xlabel('Class')
plt.ylabel('Average Satisfaction')
plt.xticks(rotation=0)
plt.tight_layout()

These lines add various details to the chart:

plt.title(‘Average Satisfaction by Class’): Sets the chart title.
plt.xlabel(‘Class’): Labels the x-axis.
plt.ylabel(‘Average Satisfaction’): Labels the y-axis.
plt.xticks(rotation=0): Sets the rotation angle of the x-axis labels to 0 degrees (no rotation). plt.tight_layout(): Adjusts the layout of the plot to make sure everything fits nicely

Step 6: Show the Chart

plt.show()

Bar chart Average satisfaction for each type of travel

# Calculate the average satisfaction for each type of travel
travel_satisfaction = data.groupby('Type of Travel')['Satisfaction'].mean()

# Create a bar chart
plt.figure(figsize=(10, 6))
travel_satisfaction.plot(kind='bar', color='skyblue')
plt.title('Average Satisfaction by Type of Travel')
plt.xlabel('Type of Travel')
plt.ylabel('Average Satisfaction')
plt.xticks(rotation=0)
plt.tight_layout()

# Show the chart
plt.show()

Bar Chart by average satisfaction for each customer type

# Calculate the average satisfaction for each customer type
customer_type_satisfaction = data.groupby('Customer Type')['Satisfaction'].mean()

# Create a bar chart
plt.figure(figsize=(10, 6))
customer_type_satisfaction.plot(kind='bar', color='skyblue')
plt.title('Average Satisfaction by Customer Type')
plt.xlabel('Customer Type')
plt.ylabel('Average Satisfaction')
plt.xticks(rotation=0)
plt.tight_layout()

# Show the chart
plt.show()

Ten Strong Arguments for Learning Python for Data Science

Despite the high average wage and high levels of job satisfaction associated with data science, there are still more companies publishing job advertising for data scientists than there are actual data scientists.

For a variety of reasons, including the fact that many FAANG-adjacent organisations use it, its versatility, and the ease with which both experienced and novice programmers can learn it, I dabbled in data science using Python.

Despite the fact that Python is a general-purpose language, this article lists 10 compelling justifications for learning it for data science along with an explanation of what Python is.

Learning Python is simple.

Being a newbie in coding might be frightening. Python, however, is an exception. Especially when compared to more complex languages like C, C++, and Java, it has an incredibly simple syntax and vocabulary, making it very easy to learn. Python is a clear choice of language for data scientists to learn.

It’s so easy to use that Next Academy actually suggests it as a fantastic way for kids to learn how to code.

Python is a wonderful coding language to start with if you want to work in data science since you can pick it up quickly and painlessly. Beginners may find it easy to learn data science with Python.

Extensive Data Science Libraries

python’s extensive collection of data science libraries is one of its biggest strengths for data scientists. Here are some of the most prominent libraries that make Python a popular choice for data science:

1.NumPy:

NumPy is a fundamental library for scientific computing in Python. It provides powerful tools for working with multi-dimensional arrays and matrices, along with a wide range of mathematical functions. NumPy forms the foundation for many other data science libraries in Python.

2. Pandas:

Pandas are a versatile library for data manipulation and analysis. It offers data structures such as DataFrames that make it easy to clean, transform, and explore tabular data. Pandas provides a wide range of functions for data alignment, filtering, aggregation, and handling missing data.

3. Matplotlib:

Matplotlib is a plotting library that enables the creation of various types of static, animated, and interactive visualizations. It offers a high degree of customization, allowing data scientists to create publication-quality plots and charts.

4. Seaborn:

Seaborn is a data visualization library built on top of Matplotlib. It provides a higher-level interface for creating visually appealing statistical graphics. Seaborn simplifies the creation of complex plots like heatmaps, violin plots, and pair plots with minimal code.

5. Scikit-learn:

Scikit-learn is a comprehensive machine-learning library in Python. It offers a wide range of algorithms and tools for tasks such as classification, regression, clustering, dimensionality reduction, and model evaluation. Scikit-learn provides a consistent API and is widely used for building and deploying machine learning models

It is simple to read.

Everything you develop with Python will make sense to you and many other people, even if they aren’t Pythonistas themselves since it has a clear, straightforward syntax that is similar to English.

Python was initially quite simple for me to learn in part because I could read Python code examples and understand what they were attempting to do. You should surely consider readability as a fundamental element of whatever language you select if you want to go into data science.

You’ll read a lot of code and converse with your coworkers about it (or strangers on the internet as you try to debug something on StackOverflow). That is simple to implement with Python.

If you learn Python, you’ll be one of many. It’s one of the most widely used languages in data science (and elsewhere). It’s the third-most widely used language in the world according to TIOBE’s 2020 index. And in data science specifically, it’s emerged as the leader, outstripping my old favorite language R.

As I alluded to above, many companies are using Python to build frameworks and projects. Google, for example, created Tensorflow, which is based on Python; Facebook and Netflix are also relying on it more and more in their data science projects.

If you want to get into data science, you won’t get far without knowing at least some Python. Luckily it’s a joy to learn!

Large Pythonista Community

There is a huge and passionate community of Pythonistas out there who are more than happy to share their tips, answer your questions, correct your code, and discuss new ideas because it has been around for three decades, is simple to learn and easy to build with, and has remained relevant to so many people and companies for such a long time. You can find them anywhere; Reddit has one of the most active communities, but you can also discover Discord groups that meet to discuss Python.

This makes learning Python for data science such an excellent option since learning any language is challenging, especially if you’re under professional pressure. That is made simpler by communities like the ones that have developed around Python.

A wider variety of data science libraries

On its own, Python excels as a language for data research. But in addition to the straightforward syntax, concise vocabulary, readability, community, and all the other advantages I’ve already mentioned, there are also libraries. In the data science communities, libraries like Pandas, statsmodels, NumPy, SciPy, and Scikit-Learn are particularly well-liked.

Data science activities are greatly simplified by ecosystems like SciPy. (SciPy is not pronounced skippy as I first thought; it is pronounced sigh-pie.) Numerous typical data science needs are addressed by SciPy, including managing data structures, analysing complicated networks, algorithms, and machine learning toolkits. Popular and dynamic Python data science libraries are available.

The truly interesting part is that as more Pythonistas join the community and contribute on their own, new Python packages for data science are constantly being released. Popular and dynamic Python data science libraries are available. For instance, the 2015 release of the simple deep learning package Keras. Since that time, it has grown to be an essential part of the Python library ecosystem.

Communication

“By providing it with a visual context through maps or graphs, data visualisation offers us a clear notion of what the information means. According to an anonymous blogger on the Analytiks blog, “This makes the data more natural for the human mind to interpret and, as a result, makes it simpler to discover trends, patterns, and outliers within enormous data sets.

Many people believe that data science ends with the analysis, but like with anything else in the professional world, what happens next is what counts.

The really simple matplotlib and its two offspring Pandas and seaborn are only a couple of the fantastic visualisation tools that Python has to offer (both built on matplotlib). The fight is half won if you can quickly create a solid viz to explain or demonstrate the facts. Python facilitates it.

Data cleanup is simple.

When I hear the term “data science,” I picture Neo from The Matrix performing awesome things while sporting a stylish coat. Many people are unaware that data science involves a LOT of less glamourous data cleansing. According to conservative estimates, 80% of a data scientist’s normal effort consists of data cleansing. The good news is that Python excels at that.

If you want to work in data science, you must accept that it will take you a lot of data scrubbing, cleaning, massaging, wrangling, etc. before you create even one cool visualisation. Python is built to clean, which is why studying it for data science is an excellent option.

NumPy and Pandas, two of the packages I previously mentioned, are excellent at cleaning data.

Teaches fundamentals

Even though Python has virtually endless applications, studying Python and data science really have a lot in common. Python’s introductory tutorials make it simple to pick up the fundamentals of data science. If you wish to utilise Python to understand data science, you may start by learning how data scientists retrieve, clean, visualise, and develop models.

By default, as you progress through the traditional path of learning Python coding, you’ll pick up the fundamentals of data science. For instance, you will first learn how to set up your environment, import data, clean it up, conduct statistical analysis on it, produce some attractive visualisations, and share your findings. And look at what you’ve accomplished.

You can easily locate a tonne of materials that teach Python and especially teach Python for data science if you keep common data science activities in mind while you search for Python lessons. A natural learning route for data science is to understand the fundamentals of Python.

Speedy prototypes

Projects involving data scientists are pricey, which is a little-known truth. In fact, “87% of data projects will fail,” according to Chris Chapo, SVP of data and analytics at Gap. Building anything that succeeds requires a lot of patience, time, effort, and resources.

To circumvent this, the majority of data scientists employ prototypes to stress-test and dry-run their ideas before actually developing them. It shouldn’t come as a surprise to you if you’ve been following the subject of this essay that Python is excellent for creating high-quality prototypes to test out concepts, ideas, and products.

Job security

Python is a great language to learn for data science, but you may use the same abilities to get work in other areas of computer science as well. Since Python has been there and relevant for thirty years and is continually reinventing itself to be helpful for new jobs and careers, it is more secure than any professional path. It’s possible that data science’s future is in doubt or that your professional objectives have changed. Python knowledge will benefit you in any situation. Start learning Python for data science, but rest assured that Python will be a useful language to know no matter what happens to the data science sector. Designed by slidesgo / Freepik
