Study Notes
Python Programming Language
- Python is a high-level, general-purpose programming language.
- It emphasizes code readability with significant indentation.
- Python is dynamically typed and garbage-collected.
- It supports 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, and Python 3.0 was released in 2008, which was a major revision not completely backward-compatible with earlier versions.
Versions and Releases
- Python 2.7.18 was the last release of Python 2, released in 2020.
- Python 3.0 and later versions have many major features backported to Python 2.6.x and 2.7.x.
- Python 2.7's end-of-life was initially set for 2015, then postponed to 2020.
- Only Python 3.8 and later are supported as of 2023, with security issues fixed in e.g. 3.7.17, the final 3.7.x release.
Security Updates
- In 2021, security updates were expedited due to security issues leading to possible remote code execution and web-cache poisoning.
- In 2022, security updates were expedited again, and Python 3.10.4, 3.9.12, and 3.8.13 were released due to many security issues.
- 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
- Python 3.11 includes increased program execution speed and improved error reporting.
- Python 3.12 adds syntax to the language, including the new (soft) keyword type, and improves exception handling.
