str and bytes are two totally unrelated things in Python 3.0. You can no
longer treat them equally like str and unicode in Python 2.x. Your could
should not work under Python 3.0 anyway. u'' is invalid in 3.x.
Also please don't use ugly type checks like type(something) == type('').
Starting with Python 2.2 you should use isinstance, for example
isinstance(number, (int, long)).
