Learn how to use the Google Analytics API with Python to access website traffic data in real-time or historical formats. Perfect for Python data analysts looking to automate reporting and analysis.
# Step 1: Install the analytics library
!pip install google-analytics-data
# Step 2: Authenticate and connect to API
from google.analytics.data_v1beta import BetaAnalyticsDataClient
from google.analytics.data_v1beta.types import DateRange, Metric, Dimension, RunReportRequest
property_id = "YOUR-GA4-PROPERTY-ID"
client = BetaAnalyticsDataClient()
request = RunReportRequest(
property=f"properties/{property_id}",
dimensions=[Dimension(name="city")],
metrics=[Metric(name="activeUsers")],
date_ranges=[DateRange(start_date="2024-07-01", end_date="2024-07-16")],
)
response = client.run_report(request)
# Step 3: Display results
for row in response.rows:
print(f"{row.dimension_values[0].value}: {row.metric_values[0].value}")

Statistical analysis helps in discovering patterns and insights from raw data. With Python, you can perform a variety of statistical tasks using libraries like Pandas, NumPy, and SciPy.
import pandas as pd
# Sample dataset
data = {'Scores': [68, 75, 80, 95, 60, 85, 70]}
df = pd.DataFrame(data)
# Basic statistics
print("Mean:", df['Scores'].mean())
print("Median:", df['Scores'].median())
print("Standard Deviation:", df['Scores'].std())
These fundamental statistical functions are essential for data analysts using Python to summarize and interpret data effectively.
Python offers a rich ecosystem of libraries and tools that make data analysis seamless. Whether you’re cleaning data, visualizing insights, or performing machine learning, the right toolkit is essential.
Essential for data manipulation and analysis—handles tables, filtering, and time series data.
Powerful support for large multidimensional arrays and high-level mathematical functions.
For data visualization—turn numbers into clear, interactive graphs and plots.
Used for advanced computations like integration, optimization, and signal processing.
The go-to machine learning library for classification, regression, and clustering tasks.
Many of these tools can also be explored on GitHub for community support and real-world projects.
For any data scientist working with Python, version control is essential. It ensures code stability, collaboration, and transparency in analytics workflows. Git and GitHub are your go-to tools.
💡 Tip: Always commit your Python scripts, data cleaning functions, and models with meaningful messages.
Predictive analytics enables businesses to forecast outcomes using data. With Python, you can build models that drive decisions using historical patterns, from customer churn to sales trends.
🚀 Start small with a linear regression model, then move to tree-based algorithms for better accuracy!
Python has transformed how data analysts work. Whether you’re using it for data visualization, Google Analytics API, or predictive modeling, it remains one of the most versatile and in-demand tools in the data world. Keep learning, experimenting, and automating your workflows to stay ahead.
