standard library for PyPy (an alternative Python 3.x interpreter)
The PyPy standard library. This is a combination of modules, copied directly from cpython, modified cpython modules, and modules entirely re-implemented (usually in pure Python, where they are C extensions in cpython).
PyPy is a fast, compliant alternative implementation of the Python language (3.x).
