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

You can use itertools.product():

from itertools import product
for xy in product(range(X), range(Y)):
    function(xy)
