    Study Notes

    General-purpose Programming Language

    • 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

    • Python was invented by Guido van Rossum in the late 1980s as a successor to the ABC programming language.
    • Guido van Rossum began working on Python in 1989 and first released it in 1991 as Python 0.9.0.
    • Python 2.0 was released in 2000, and Python 3.0, released in 2008, was a major revision not completely backward-compatible with earlier versions.

    Releases

    • Python 2.7.18, released in 2020, was the last release of Python 2.
    • Python 3.8 and later are currently supported (as of 2023).
    • Security issues were fixed in Python 3.7.17, the final 3.7.x release.
    • Python 3.10.4, 3.9.12, and 3.8.13 were expedited in 2022 due to security issues.
    • Python 3.9.13, released in May 2022, marked the end of non-security updates for the 3.9 series.

    Current Status

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