Pythonic shortcut for doubly nested for loops?
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 onYour code would look like:
for x,y in product(range(X), range(Y)): function(x,y)
You can use itertools.product():
from itertools import productfor xy in product(range(X), range(Y)): function(xy)
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 00 11 01 1
