I think the other Pythonic option you have missed is to convert the nested 
for loops into a single loop by writing a generator.

def ranges(limit1, limit2):
     range1, range2 = range(limit1), range(limit2)
     for i in range1:
         for j in range2:
             yield i,j

...
    for i, j in ranges(10, 10):
        ... whatever ...
        if j==6:
            break
