Rémi Lapeyre <remi.lape...@henki.fr> added the comment: This is because you used the floating point division operator `/` instead of the integer division `//`:
def digitsum(num): digsum = 0 tnum = num while tnum > 0: print("tnum = %d, digsum = %d" % (tnum,digsum)) digsum += (tnum % 10) tnum = int((tnum - (tnum % 10)) // 10) return digsum gives the result you expect. Please ask for help on StackOverflow or the python-help mailing list first as this bug tracker is for reporting bugs in the Python interpreter itself and not for general help with Python programming. The various numeric operator are documented at https://docs.python.org/3/library/stdtypes.html#numeric-types-int-float-complex ---------- nosy: +remi.lapeyre _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue41201> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
