Questions tagged [python-sockets]

For questions related to the sockets module in the Python standard library, or more broadly socket programming in Python.

The Python library comes with a HOWTO document for sockets programming:

Socket Programming HOWTO — Python 3.x documentation

The standard library is well-documented:
