Multiprocessing with multiple arguments to function in Python 2.7

Question

I\'m trying to implement multiprocessing to speed up a replication loop, but cannot get it to work in Python27. This is a very simplified version of my program, based on the

Answer 1

The problem is solved by adding a main() function as:

import itertools
from multiprocessing import Pool

def func(g, h, i):
    return g + h + i

def helper(args):
    args2 = args[0] + (args[1],)
    return func(*args2)

def main():
    pool = Pool(processes=4)
    result = pool.map(helper,itertools.izip(itertools.repeat((2, 3)), range(10)))
    print result

if __name__ == '__main__':
    main()

Based on the answer from @ErikAllik I'm thinking that this might be a Windows-specific problem.

edit: Here is a clear and informative tutorial on multiprocessing in python.
