Trying the multiprocessing module for the first time, I spent quite a
bit on making this code run:
[...]
The result was not what I expected, it seems like the process restarts
all the time, and the message 'Process started' keeps getting
printed...
Going back to the documentation, I realized that the doc was really
serious about the line:
if __name__ == '__main__' .. which I always ignore, and by changing
the code to
if __name__ == '__main__':
p = Process(target=my_process, args=())
p.start()
print 'Process started'
the problem was solved.
So my question is what actually happens when I call p.start()? Is the
entry file reloaded under a different module name?
The multiprocessing module handles multiple (separate) processes. On
Windows, a new Python interpreter is launched; on other OSs a different
approach is used. In any case, you get distinct and separate processes,
each one with its own set of loaded modules, etc.
