Er, ignore this. Division in Python 3 only returns a float if the remainder is non-zero, and when dividing by the gcd the remainder should always be zero. > Here's a hint: your unit tests should also assert that > the result of lcm is always an int.) Still good advise. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
