    Study Notes

    General-Purpose Programming Language

    • Python is a high-level, general-purpose programming language that emphasizes code readability using significant indentation.

    Design and Features

    • Python is dynamically typed and garbage-collected.
    • Supports multiple programming paradigms: structured, object-oriented, and functional programming.
    • Often described as a "batteries included" language due to its comprehensive standard library.

    History

    • Invented in the late 1980s by Guido van Rossum as a successor to the ABC programming language.
    • Guido van Rossum was the lead developer and "benevolent dictator for life" (BDFL) until 2018.
    • In 2019, a five-member Steering Council was elected to lead the project.

    Releases

    • Python 2.0 was released in 2000 with features like list comprehensions and Unicode support.
    • Python 3.0 was released in 2008 with many backported features to Python 2.6.x and 2.7.x.
    • Python 2.7.18 was the last release of Python 2 in 2020.
    • Python 3.8 and later are currently supported (as of 2023).
    • Python 3.9 series and older will only receive security fixes.

    Security Updates

    • In 2021 and 2022, security updates were expedited due to security issues leading to remote code execution and web-cache poisoning.
    • Releases 3.10.4, 3.9.12, and 3.8.13 were expedited due to many security issues.
    • Releases 3.10.7, 3.9.14, 3.8.14, and 3.7.14 were made due to a potential denial-of-service attack.

    Notable Changes

    • Python 3.11 added increased program execution speed, improved error reporting, and expanded exception handling functionality.
    • Python 3.10 added the | union type operator and match and case keywords for structural pattern matching statements.
    • Python 3.12 added the new keyword type.
