# 17.10. `dummy_threading` — Drop-in replacement for the `threading` module

Source code: Lib/dummy_threading.py

Deprecated since version 3.7: Python now always has threading enabled. Please use `threading` instead.

This module provides a duplicate interface to the `threading` module. It was meant to be imported when the `_thread` module was not provided on a platform.

Be careful to not use this module where deadlock might occur from a thread being created that blocks waiting for another thread to be created. This often occurs with blocking I/O.
