# 16.5. `dummy_thread` — Drop-in replacement for the `thread` module

Note

The `dummy_thread` module has been renamed to `_dummy_thread` in Python 3.0. The 2to3 tool will automatically adapt imports when converting your sources to 3.0; however, you should consider using the high-lever `dummy_threading` module instead.

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 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.
