Is there any truncation for nested classes?

Question

Recently, I saw several people doing similar things here in Stackoverflow:

class A:
    foo = 1

    class B:
        def blah(self):
            pass

In other words, they have nested classes. This works (although people new to Python seem to run into problems because they don't behave the way they thought), but I can't think of any reason to do this in any language whatsoever and, of course, not in Python . Is there such a truncation? Why do people do this? The search for this seems to him quite common in C ++, is there a good reason there?
