Perhaps you can start with pseudo-code (http://en.wikipedia.org/wiki/Pseudo_code) and ask for help writing that in Python. I'll get you started. Ask for a number. If number = 0, stop. If number < 0, ask again. With values 50, 25, 10, 5 and 1: if number > value: coincount = integer portion of number divided by value print coincount, value remaining number = ... I've broken the pseudo-code into two parts because they are, in some sense, different programs. You might try to write one, then the other. In other words, starting by writing this in Python: Ask for a number. If number = 0, stop. If number < 0, ask again. If number > 0, print number and quit. -- http://mail.python.org/mailman/listinfo/python-list
