:mod:`dummy_threading` --- Drop-in replacement for the :mod:`threading` module
==============================================================================
.. module:: dummy_threading
:synopsis: Drop-in replacement for the threading module.
**Source code:** :source:`Lib/dummy_threading.py`
.. deprecated:: 3.7
Python now always has threading enabled. Please use :mod:`threading` instead.
--------------
This module provides a duplicate interface to the :mod:`threading` module.
It was meant to be imported when the :mod:`_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.
