Study Notes
Python Overview
- Python is a high-level, general-purpose programming language that emphasizes code readability using significant indentation.
- It is dynamically typed and garbage-collected, supporting multiple programming paradigms (structured, object-oriented, and functional).
- Python is known for its comprehensive standard library, making it a "batteries included" language.
History of Python
- Guido van Rossum began working on Python in the late 1980s as a successor to the ABC programming language.
- The first release, Python 0.9.0, was in 1991.
- Python 2.0 was released in 2000, and Python 3.0, a major revision, was released in 2008.
- Guido van Rossum was the lead developer until 2018, when he stepped down, and a five-member Steering Council was elected to lead the project.
Python Releases
- Python 2.7.18, released in 2020, was the last release of Python 2.
- Python 3.x releases include the 2to3 utility, which automates the translation of Python 2 code to Python 3.
- Python 2.7 and older is officially unsupported, but unofficial implementations like PyPy continue to support Python 2.
- 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 3.10.4 and 3.9.12 were expedited due to security issues, and Python 3.9.13 marked the 3.9 series receiving only security fixes.
- Python 3.10 and 3.11 introduced changes, including increased program execution speed, improved error reporting, and syntax additions.
