Python doesn't have anything like C's scanf that can read input into variables of fixed types. Anything that you read from the user (using raw_input[1]), will be returned as a string. So even if the user types 2 and hits enter, you will get back "2" (which is a string). To check whether this can be converted into a number, the usual way is to try to use it like a number and catch the exception which will be raised if the conversion fails. Here is a simple example. >>> x = "2" >>> try: ... int(x) ... except ValueError: ... print "Not a number" ... 2 >>> x = "abcd" >>> try: ... int(x) ... except ValueError: ... print "Not a number" ... Not a number [...] Footnotes: [1] http://docs.python.org/2/library/functions.html#raw_input -- Cordially, Noufal http://nibrahim.net.in _______________________________________________ BangPypers mailing list BangPypers@python.org http://mail.python.org/mailman/listinfo/bangpypers
