Python is a widely uised heich-level programmin leid for general-purpose programmin, creatit bi Guido van Rossum an first released in 1991. An interpretit leid, Python haes a design filosofie which emphasizes code readability (notably uisin whitespace indentation tae deleemit code blocks rather nor curly braces or keywirds), an a syntax which allaes programmers tae express concepts in fewer lines o code nor possible in leids sic as C++ or Java.[23][24] The leid provides constructs intendit tae enable writin clear programs on baith a smaw an lairge scale.[25]

Python featurs a dynamic teep seestem an automatic memory management an supports multiple programmin paradigms, includin object-orientit, imperative, functional programmin, an procedural styles. It haes a lairge an comprehensive staundart leebrar.[26]

Python interpreters are available for mony operatin seestems, allaein Python code tae run on a wide variety o seestems. CPython, the reference implementation o Python, is open soorce saftware[27] an haes a commonty-based development model, as dae nearly aw o its variant implementations. CPython is managed bi the non-profit Python Software Foundation.

The Swift language is the product of tireless effort from a team of language experts, documentation gurus, compiler optimization ninjas, and an incredibly important internal dogfooding group who provided feedback to help refine and battle-test ideas. Of course, it also greatly benefited from the experiences hard-won by many other languages in the field, drawing ideas from Objective-C, Rust, Haskell, Ruby, Python, C#, CLU, and far too many others to list.
