# Python - High-level, interpreted programming language

"""
Python is a high-level, interpreted programming language known for its simplicity and readability.
Created by Guido van Rossum and first released in 1991, Python emphasizes code readability
with its notable use of significant whitespace. It supports multiple programming paradigms,
including procedural, object-oriented, and functional programming.

Key Features:
- Easy to learn and use
- Interpreted language
- Dynamically typed
- Extensive standard library
- Cross-platform compatibility
- Strong community support
