This document is for an old version of Python that is no longer supported. You should upgrade, and read the Python documentation for the current stable release.

# `_dummy_thread` — Drop-in replacement for the `_thread` module

Source code: Lib/_dummy_thread.py

Deprecated since version 3.7: Python now always has threading enabled. Please use `_thread` (or, better, `threading`) instead.

This module provides a duplicate interface to the `_thread` 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.
