Working around a lack of 'goto' in python

If you're not doing anything between the loops, I like to use a
generator:

def iindices(klimit, jlimit, ilimit):
    for k in xrange(klimit):
        for j in xrange(jlimit):
            for i in xrange(ilimit):
                yield k, j, i

for k, j, i in iindices(klimit, jlimit, ilimit):
    if test_fails(k, j, i):
        break
