- 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.
