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

注解

The dummy_thread module has been renamed to _dummy_thread in Python 3. The 2to3 tool will automatically adapt imports when converting your sources to Python 3; however, you should consider using the high-lever dummy_threading module instead.

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 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.
