Study Notes
Language Features
- Python is a high-level, general-purpose programming language that emphasizes code readability with significant indentation.
- It is dynamically typed and garbage-collected.
- Supports multiple programming paradigms: structured, object-oriented, and functional programming.
History
- Guido van Rossum invented Python in the late 1980s as a successor to the ABC programming language.
- Van Rossum led the project until 2018, then became "BDFL-emeritus" and a five-member Steering Council was elected to lead the project in 2019.
Releases
- Python 0.9.0 was first released in 1991.
- Python 2.0 was released in 2000 with new features like list comprehensions and Unicode support.
- Python 3.0 was released in 2008, with 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.
- Currently, only Python 3.8 and later are supported, with 3.12 being the stable release.
- Older versions (2.7, 3.7, 3.8) only receive security fixes.
Updates and Security
- PyPy, an unofficial Python implementation, continues to support Python 2 with backported 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 expedited due to multiple 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 syntax for increased program execution speed and improved error reporting.
- Python 3.10 added the | union type operator and the match and case keywords.
- Python 3.11 expanded exception handling functionality.
- Python 3.12 added the new keyword type.
