what module is NoneType in?

[Skaperen]

for testing i can just do:

    if foo is None:
        break

but i want to know which module will correctly define NoneType. or do i need to do:

NoneType = type(None)

The answer is that you need to do NoneType = type(None) if you want a variable name for this type.
