• Unifying types and classes in Python 2.2

  ...setattr__: sometimes attributes are not stored in self.__dict__ (for example when using __slots__ or properties, or when using a built-in base class). The same pattern as for __getattribute__ applies, where you call the base class __setattr__ to do the actual work. Here's an example: class C(object): def __setattr__(self, name, value): if hasattr(self, name): raise AttributeError, "attributes are write-once" object.__setattr__(se...

• Python 2.0

  ...setattr() now also accept Unicode objects for the attribute name, which are converted to strings using the default encoding before lookup. Multiplication on string and Unicode now does proper bounds checking; e.g. 'a' * 65536 * 65536 will raise ValueError, "repeated string is too long." Better error message when continue is found in try statement in a loop. Standard library and extensions array: reverse() method of array now works. buffer_info() now does ...
