Here is the python doc :

pipes — Interface to shell pipelines

This module is no longer part of the Python standard library. It was removed in Python 3.13 after being deprecated in Python 3.11. The removal was decided in PEP 594.

Applications should use the subprocess module instead.

The last version of Python that provided the pipes module was Python 3.12.
