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

Pythonic they are -> (modify according to your requirements)

>>> [ (x,y)   for x in range(2)   for y in range(2)]
[(0, 0), (0, 1), (1, 0), (1, 1)]

Generator version :

gen = ( (x,y)   for x in range(2)   for y in range(2) )
>>> for x,y in gen:
...     print x,y
... 
0 0
0 1
1 0
1 1
