Editing Python (programming language) (section)

==Libraries==
Python's large standard library<ref name="AutoNT-86"/> is commonly cited as one of its greatest strengths. For Internet-facing applications, many standard formats and protocols such as [[MIME]] and [[HTTP]] are supported. The language includes modules for creating [[graphical user interface]]s, connecting to [[relational database]]s, [[pseudorandom number generator|generating pseudorandom numbers]], arithmetic with arbitrary-precision decimals,<ref name="AutoNT-88"/> manipulating [[regular expression]]s, and [[unit testing]].

Some parts of the standard library are covered by specifications—for example, the [[Web Server Gateway Interface]] (WSGI) implementation <code>wsgiref</code> follows PEP 333<ref name="AutoNT-89"/>—but most parts are specified by their code, internal documentation, and [[test suite]]s. However, because most of the standard library is cross-platform Python code, only a few modules must be altered or rewritten for variant implementations.

{{As of|2025|03|13|post=,}} the [[Python Package Index]] (PyPI), the official repository for third-party Python software, contains over 614,339<ref name="PyPI">{{cite web |date=2025-03-13 |title=PyPI |url=https://pypi.org/ |url-status=live |archive-url=https://web.archive.org/web/20250222013445/https://pypi.org/ |archive-date=2025-02-22 |website=PyPI}}</ref> packages.
