The types module pre-dates the time when classes were actually types in their
own right, and many of the built-in constructors, like "float", "int", and
"list", were simply functions. When that was the case:
>>> import types
>>> types.IntType == int
False
For types that have always been types, there's no corresponding entry in the
types module, nor is there any need for any, since the type itself is already
accessible.
