This is how I would do it: def prttn(m, n): """How many positive integers less than n have digits that sum up to m""" total = 0 for testval in range(n): sumofdigits = sum(int(char) for char in str(testval)) if sumofdigits == m: total += 1 return total I added a docstring to the function, saying what it does, and what the arguments are supposed to represent. I also moved the convert-to-string-and-sum-the-digits logic into a single generator expression that's passed to the builtin sum function. Oh, and I tried to use slightly more expressive variable names. -- Jerry -- http://mail.python.org/mailman/listinfo/python-list
