Python nested looping Idiom

Question

I often find myself doing this:

for x in range(x_size):
    for y in range(y_size):
        for z in range(z_size):
            pass # do something here
         


        

Answer 1

It depends on what is inside the loop. If dealing with lists, you may be able to use a list comprehension

For the more general case, see this post on itertools.
