I was trying to run a piece of code.This code is all about multiprocessing.It works fine on command prompt and it also generates some output.But when I try to run this code on pyscripter it just says that script runs ok and it doesn't generate any output nor even it displays any error message.It doesn't even crashes.It would be really helpful if anyone could help me out to find out a right interpreter where this multiprocessing works fine.
Here is the piece of code:
from multiprocessing import Process
The normal interpreter works just fine with
multiprocessing on Windows 7 for me. (Your IDE might not like multiprocessing.)
You just have to do
if __name__=='__main__': main()
with 2 underscores (
__) each instead of 1 (
Also - if you don't have an actual reason not to use it,
multiprocessing.Pool is much easier to use than
multiprocessing.Process in most cases. Have alook at https://docs.python.org/2/library/multiprocessing.html#module-multiprocessing.pool
An implementation with a Pool would be
import multiprocessing def wait(): print "wait" clean() def clean(): print "clean" def main(): p=multiprocessing.Pool() p.apply_async(wait) p.close() p.join() if __name__=='__main__': main()
but which method of Pool to use strongly depends on what you actually want to do.
