Python – Hello World Program

This tutorial will teach you how to write a simple Hello World program using the Python programming language. This program will make use of Python’s built-in print() function to print the string.

Hello World Program in Python

Printing “Hello World” is the first program in Python. This program will not take any user input but will print text on the output screen. It is often used to test if the Python installation and environment are correctly set up.

Steps

1. Install Python. Download Python from the official website: python.org/downloads.
2. Choose a text editor or IDE to write the code.
3. Create a new file and write the code to print Hello World.
4. Save the file with the extension .py.
5. Compile and run the program.

Python Code to Print Hello World

# Python code to print "Hello World"
print("Hello World")
  

Output

Hello World
  

Different Ways to Write and Execute Hello World Program

Using Python Interpreter Command Prompt Mode

You can directly run the print() function in the Python interpreter. Here’s how it looks:

PS C:\> python
Python 3.11.2 (tags/v3.11.2:878ead1) [MSC v.1934 64 bit] on win32
Type "help", "copyright", "credits" or "license" for more information.

>>> print("Hello World")
Hello World
  

Using Python Interpreter Script Mode

Save the code in a file named hello.py and execute it using the following commands:

• On Windows:

  C:\> python hello.py
  Hello World
        

• On Linux:

  $ python3 hello.py
  Hello World
        

Using Shebang #! in Linux Scripts

Add a shebang line to make the script executable directly:

#!/usr/bin/python3

print("Hello World")
  

Make the file executable with:

$ chmod +x hello.py
$ ./hello.py
Hello World
