    Study Notes

    Python Overview

    • Python is a high-level, general-purpose programming language that emphasizes code readability with significant indentation.
    • It is dynamically typed and garbage-collected, supporting multiple programming paradigms, including structured, object-oriented, and functional programming.
    • Python is often described as a "batteries included" language due to its comprehensive standard library.

    History

    • Guido van Rossum began working on Python in the late 1980s as a successor to the ABC programming language.
    • Python 0.9.0 was first released in 1991, with Python 2.0 released in 2000.
    • Python 3.0, released in 2008, was a major revision not completely backward-compatible with earlier versions.
    • Python 2.7.18, released in 2020, was the last release of Python 2.

    Development and Governance

    • Guido van Rossum was the lead developer and "benevolent dictator for life" until 2018.
    • In 2019, a five-member Steering Council was elected to lead the project.
    • Van Rossum has since come out of retirement and is self-titled "BDFL-emeritus".

    Releases and Support

    • Python 2.7's end-of-life was initially set for 2015, then postponed to 2020.
    • Currently, only Python 3.8 and later are supported, with security issues fixed in earlier versions.
    • PyPy, an unofficial Python implementation, continues to support Python 2, including backported security updates.

    Security Updates

    • In 2021 and 2022, security updates were expedited due to security issues in all Python versions.
    • Releases 3.10.4, 3.9.12, and 3.8.13 were made to address security issues.
    • The 3.9 series will only receive security fixes in the future.

    Latest Releases

    • As of October 2023, Python 3.12 is the stable release, with active support only for 3.12 and 3.11.
    • Notable changes in 3.11 include increased program execution speed and improved error reporting.
    • Python 3.12 adds new syntax to the language, including a new soft keyword type and improved typing support.
