Programming Fundamentals/Introduction Examples Python

Overview

Python is an interpreted high-level programming language for general-purpose programming. Created by Guido van Rossum and first released in 1991, Python has a design philosophy that emphasizes code readability, notably using significant whitespace. It provides constructs that enable clear programming on both small and large scales.

Python is one of the most popular current programming languages, is frequently recommended as a first programming language, and often used in information systems and data science courses.
