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

Source code: Lib/_dummy_thread.py

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

Suggested usage is:

    try:
        import _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.
