What is Python?

Python is a high-level programming language used to write computer programs. It is one of the most popular and beginner-friendly languages in the world.

Python was created by Guido van Rossum in 1991. The main goal of Python is to make programming simple, readable, and powerful.

Unlike many other programming languages, Python uses simple English-like syntax, so beginners can learn it easily.

Example of a Python program:

print("Hello World")

This program simply prints Hello World on the screen.
