Welcome to Python Programming!

Python is one of the most popular and beginner-friendly programming languages in the world. In this course, you'll learn Python from the ground up, step by step.

What is Python?

Python is a high-level, interpreted programming language created by Guido van Rossum. It's known for its:

✨ Simple Syntax: Code reads like English
🚀 Versatility: Used in web development, data science, AI, automation, and more
💪 Power: Used by Google, Netflix, NASA, and thousands of companies
👥 Community: Huge supportive community and extensive libraries

Your First Python Program

The simplest Python program uses the print() function:

print('Hello, World!')
print('Welcome to Python!')

Python Syntax Basics

No Semicolons: Python doesn't need semicolons (;)
Indentation Matters: Python uses indentation (spaces) to organize code
Comments: Use # for single-line comments
Quotes: Use single (') or double (") quotes for text

Basic Output

The print() function displays text on the screen:

# Print a simple message
print('Hello, Python!')

# Print multiple items
print('Name:', 'John')
print('Age:', 25)

# Print on same line (using end parameter)
print('Hello', end=' ')
print('World')
