Instead of doing this:
for x in range(500):
for y in range(300):
print x,y
How can i do something like this?
for x,y in range(500),range(300):
print x,y

I would use itertools.product
from itertools import product
for x, y in product(range(500), range(300)):
print x, y

Using list comprehension:
pairs = [ (i,j) for i in range(300) for j in range(300) ]
print pairs
This is the test I have run:
print [ (i,j) for i in range(3) for j in range(3) ]
output
[(0, 0), (0, 1), (0, 2), (1, 0), (1, 1), (1, 2), (2, 0), (2, 1), (2, 2)]
Using itertools' product
print [ (i,j) for i, j in itertools.product(range(300), range(300))]

doesn't zip only work for lists with the same size? Also I prefer it being in the format i said because I need to do a lot of stuff there and list comprehension is a little bit limited since i can only put one line of code.

Yeah, I changed my answer, since
zip doesn't do what you asked.
