Study Notes
General Features of Python
- 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
- Python was invented in the late 1980s by Guido van Rossum at Centrum Wiskunde & Informatica (CWI) in the Netherlands.
- Van Rossum was the sole lead developer until 2018, when he stepped down as the "benevolent dictator for life" (BDFL).
- A five-member Steering Council was elected in 2019 to lead the project.
Releases of Python
- Python 2.0 was released in 2000 with many major new features, including list comprehensions, cycle-detecting garbage collection, and Unicode support.
- Python 3.0 was released in 2008 with many major new features, and its end-of-life was initially set for 2015, then postponed to 2020.
- Python 2.7's end-of-life was in 2020, and no further security patches or improvements will be released for it.
- Currently, only Python 3.8 and later versions are supported, with security issues being fixed in newer versions.
Unofficial Python Implementation
- PyPy, an unofficial Python implementation, continues to support Python 2 with backported security updates.
Security Updates
- In 2021 and 2022, security updates were expedited due to security issues in all Python versions, including 2.7.
- The 3.9 series will 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 support.
Recent Changes
- Python 3.11 includes increased program execution speed and improved error reporting.
- Python 3.12 adds new syntax, including a new type union operator, and improves exception handling and typing support.
