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

If you've got numpy as a dependency already, numpy.ndindex will do the trick ...

>>> for x,y,z in np.ndindex(2,2,2):
...     print x,y,z
