- 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.
