Balík: pypy3-lib (7.3.9+dfsg-1)

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).
