Pythonic shortcut for doubly nested for loops?

Question

Consider if I had a function that took a tuple argument (x,y), where x was in the range(X), and y in the range(Y), the normal way of doing it would be:

for x in          


        

Answer 1

from itertools import product

def something_like_range(*sizes):
    return product(*[range(size) for size in sizes])

for a usage close to what you wanted:

for x,y in something_like_range(X,Y):
    your_function(x,y)
