I literally said “It doesn’t create an instance of anything”. Back on
the 3rd, Dennis told you when instances (of the PWM type) were actually
created. He also quoted the documentation of PyType_GenericNew,
clarifying that it was a function, another thing that apparently only
registered when Steve told you.

If you had mentioned that you thought it was a class then things might
have gone a bit quicker. The idea that you’d have that particular
misconception simply didn’t occur to me because (1) you’d already seen
the documentation for it, so if you’d been paying attention you’d know
what is was and (2) there is no such thing as a class in the C language.

I’m not asking that you “just understand”, I am asking that you pay
attention to what is being said. When there’s one right answer to a
question then it’s inherent that there’s going to be some repetitiveness
in any discussion about it, because the right answer doesn’t change.
