performance - Iterating bidimensional array/list with only one for (Python) -

-

this question has answer here:

instead of doing this:

for x in range(500):     y in range(300):         print x,y

how can this?

for x,y in range(500),range(300):     print x,y

i use itertools.product

from itertools import product x, y in product(range(500), range(300)):     print x, y
