Immutable Set Test Algorithm
create by Guido van Rossum and first released in 1991, Python's design doctrine emphasizes code readability with its notable purpose of significant whitespace.and later are backed. In January 2019, active Python core developers elected Brett Cannon, Nick Coghlan, Barry Warsaw, Carol Willing and Van Rossum to a five-member" steer Council" to lead the project. Van Rossum shouldered sole responsibility for the project, as the lead developer, until 12 July 2018, when he announced his" permanent vacation" from his responsibility as Python's Benevolent Dictator For life, a title the Python community bestowed upon him to reflect his long-term commitment as the project's chief decision-maker. Python 2.0 was released on 16 October 2000 with many major new features, including a cycle-detecting garbage collector and support for Unicode.
