python multiprocessing - run logic when process terminates

Question

When using Python multiprocessing, what is the proper way to ensure code will run to cleanup whenever a process exits (both cleanly or on fatal error.)

If I am writing my processes as inheriting from the Process object, should I put this functionality in the __del__ method of the object? I tried putting simple log statements into terminate , but it doesn't seem to execute when the script receives a SIGHUP or KeyboardInterrupt .

Answer 1

Python有atexit -handlers，根据我的经验，这是非常可靠的。
