Hello World Program

The Hello World program demonstrates the basic structure of a Python program.

# This is a comment. It will not be executed.
print("Hello, World!") 

Hello, World!

How does this work:

• print() is a built-in Python function that instructs the computer to display text on the screen.
• "Hello, World!" is a string enclosed within quotes (either single ' or double ").
• Python uses indentation (spaces or tabs) to define code blocks instead of braces {} in C, C++ and Java .
• # is used to write Python Comments. Comments are ignored during execution.
