:mod:`dummy_thread` --- Drop-in replacement for the :mod:`thread` module
========================================================================
.. module:: dummy_thread
:synopsis: Drop-in replacement for the thread module.
.. note::
The :mod:`dummy_thread` module has been renamed to :mod:`_dummy_thread` in
Python 3.0. The :term:`2to3` tool will automatically adapt imports when
converting your sources to 3.0; however, you should consider using the
high-lever :mod:`dummy_threading` module instead.
**Source code:** :source:`Lib/dummy_thread.py`
--------------
This module provides a duplicate interface to the :mod:`thread` module. It is
meant to be imported when the :mod:`thread` module is not provided on a
platform.
Suggested usage is::
try:
import thread as _thread
except ImportError:
import dummy_thread as _thread
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.
