if you want to ask three questions, asking three questions seem to be a rather good way to do it... > Can a user be prompted thrice with a single raw_input and something > additional? you could use the input() function to read an integer tuple: >>> a, b, c = input("enter three comma-separate values: ") enter three comma-separate values: 1, 2, 3 >>> a 1 >>> b 2 >>> c 3 but this is pretty fragile: >>> a, b, c = input("enter three comma-separate values: ") enter three comma-separate values: 1, 2 Traceback (most recent call last): File "<stdin>", line 1, in ? ValueError: unpack tuple of wrong size >>> a, b, c = input("enter three comma-separate values: ") enter three comma-separate values: hello Traceback (most recent call last): File "<stdin>", line 1, in ? File "<string>", line 0, in ? NameError: name 'hello' is not defined to work around this, you can place the input statement in a loop and use try-except to catch any errors: while 1: try: a, b, c = input("enter 3 values: ") except KeyboardInterrupt: raise except: print "invalid input; try again" else: break but at this point, maybe using three separate calls aren't such a bad idea anyway... </F> -- http://mail.python.org/mailman/listinfo/python-list
