Right, range() only works with integer arguments. You can use a list comprehension to convert to floats: In [2]: print [ x/10.0 for x in range(10, 20) ] [1.0, 1.1000000000000001, 1.2, 1.3, 1.3999999999999999, 1.5, 1.6000000000000001, 1.7, 1.8, 1.8999999999999999] The rounding errors are to be expected, see this link for an explanation: http://docs.python.org/tutorial/floatingpoint.html Kent _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
