Python Class 5

Python's large standard library[130] provides tools suited to many tasks and 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. It includes modules for creating graphical user interfaces, connecting to relational databases, generating pseudorandom numbers, arithmetic with arbitrary-precision decimals,[126] manipulating regular expressions, and unit testing.
Some parts of the standard library are covered by specifications-for example, the Web Server Gateway Interface (WSGI) implementation wsgiref follows PEP 333[131]-but most are specified by their code, internal documentation, and test suites. However, because most of the standard library is cross-platform Python code, only a few modules need altering or rewriting for variant implementations.
As of 17 March 2024, the Python Package Index (PyPI), the official repository for third-party Python software, contains over 523,000[132] packages with a wide range of functionality, including:
