Tthe isdigit() method of a string provides a simple test. It will return true if each character is a digit. if first_part.isdigit(): # post data If you want to allow things like '-300' or '1.234' then you can try to convert to an int or float. Failure will raise a ValueError. try: float(first_part) # post data except ValueError: pass Kent _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
