Allowing floats can also lead to type errors for operations that require an integral type, but at least they're easier to catch with proper testing. For example, line 323 will raise a TypeError if n is a float: http://code.google.com/p/pyprimes/source/browse/src/pyprimes.py#323 1.0 == 1, but range(1.0) is not allowed and neither is [0,1][1.0]. _______________________________________________ Tutor maillist - [email protected] To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
