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.
History of Python
- 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.
- Python 2.0 was released in 2000, with many major new features such as list comprehensions and Unicode support.
- Python 3.0 was released in 2008, with many of its major features backported to Python 2.6.x and 2.7.x.
Releases and Support
- Python 2.7's end-of-life was initially set for 2015, then postponed to 2020.
- Python 2.7.18, released in 2020, was the last release of Python 2.
- Currently, only Python 3.8 and later are supported (2023 security issues were fixed in e.g. 3.7.17, the final 3.7.x release).
- PyPy, an unofficial Python implementation, continues to support Python 2, i.e. "2.7.18+" (plus 3.9 and 3.10).
Recent Developments
- In 2021 and 2022, security updates were expedited due to security issues leading to possible remote code execution and web-cache poisoning.
- Python 3.10.4 and 3.9.12 were expedited and 3.8.13 due to many security issues.
- Python 3.9.13 was released in May 2022, announcing that the 3.9 series would only receive security fixes in the future.
- As of October 2023, Python 3.12 is the stable release, and 3.12 and 3.11 are the only versions with active (as opposed to just security) support.
- Notable changes in 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 improved error reporting.
