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 product from itertools

>>> from itertools import product
>>> 
>>> for x,y in product(range(3), range(4)):
...   print (x,y)
... 
(0, 0)
(0, 1)
(0, 2)
(0, 3)
(1, 0)
(1, 1)
(1, 2)
(1, 3)

... and so on

Your code would look like:

for x,y in product(range(X), range(Y)):
    function(x,y)
