What Is Python?

Python is one of the easiest and most popular programming languages in the world. It is used for:

• backend web development
• automation & scripting
• AI and machine learning
• game development
• data analysis
• desktop applications

Python is loved because its code looks almost like plain English. Perfect for beginners.

Your First Python Program

The “Hello World” program is the classic first step. It prints text to the screen.

print("Hello, World!")
      

Explanation:

• print() is a built-in Python function
