In Python there seems to be no guarantee that different objects also have different hash values.
Well, it's true that you can override the __hash__ method to do whatever you want, but I believe the default for class __hash__ methods is to return the class id, which should be different for each class:
py> class C(object): ... pass ... py> hash(C) 12699152 py> id(C) 12699152
