Getty fully qualified class name from class object

How can I programmatically get the fully qualified name of a class from its class object? (I'm referring to the name that is shown when str() or repr() is called on the class object.) Neither the __name__ or __qualname__ class attributes include the module. For example: >>> import logging

Which more Pythonic - self.__class__ or type(self)?

Seems like an FAQ, and I've found a few things on StackOverflow that discuss the technical differences in edge cases, but I haven't found anything that talks about which form is considered to be more Pythonic in those situations where there's no functional difference. Is there any consensus? --

I just discovered this behavior, which is problematic for my particular use. Is there a different set API (or operator) that can be used to add an element to a set, and replace any equal element? If not, am I correct that I should call set.discard() before calling set.add() to achieve the behavi
