How to make n-dimensional nested for-loops in Python? [duplicate]

Answer 1

Use multiprocessing!

import multiprocessing
from itertools import product

results = [] 
def callback(return_value):
    # this stores results
    results.append(return_value)

if __name__=="__main__" :
    pool = multiprocessing.Pool(4)
    args = product(range1, range2, range)
    for x, y, z in args:
        pool.apply_async(f,(x,y,z),call_back=callback)
    pool.close()
    pool.join()

Now you can run your function while also taking advantage of the full capacity of your machine!
