    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.[1]

    Python is one of the most popular current programming languages[2], is frequently recommended as a first programming language, and often used in information systems and data science courses.

    Example

    Hello World

    # This program displays "Hello world!"

    print("Hello world!")

    Output

    Each code element represents:[3]

    • # begins a comment

    • "Hello world!" is the literal string to be displayed
