🔹 What is Python?

Python is a high-level, interpreted programming language created by Guido van Rossum and first released in 1991.

It focuses on code readability and simplicity, which makes it ideal for beginners and professionals alike.

Unlike other languages that can feel strict or complex, Python lets you write code that looks almost like plain English.

For example:

print("Hello, World!")

That’s it - your first Python program! No semicolons, no curly braces, just a simple command that prints text to the screen.
