Python Introduction & Syntax
Why Python is the #1 language for AI, data science, and backend development
Python is a popular programming language created by Guido van Rossum and released in 1991. It is known for its clean, readable syntax that resembles plain English.
Python Syntax & Indentation

Indentation is mandatory in Python. Failing to indent correctly produces an IndentationError.
