为什么str(cut)会报错? 但cut.__str__()不会?

You should indicate that this is Python 2.
str is actually a class. Since it is a class, its result should naturally return an instance of type str. So it will try to convert the result of your cut.__str__() (unicode type) into str. An error was reported at this step.
