Thanks to Richard Damon and Peter Holzer for your replies. I'm working through
the call chain to understand better so I can post a followup question if
needed.
Thanks again.

Based on your explanations, I went through the call chain and now I understand
better how it works, but I have a follow-up question at the end.
This code comes from the DeltaBlue benchmark in the Python benchmark suite.

The call chain starts in a non-class program with the following call

At the final line it calls "satisfy" in the Constraint class, and that
line calls choose_method in the BinaryConstraint class. Just as Peter
Holzer said, it requires a call to "satisfy."
My only remaining question is, did it select the choose_method in th

Thanks for your reply. You are correct about the class definition lines – e.g.
class EqualityConstraint(BinaryConstraint). I didn’t post all of the code
because this program is over 600 lines long. It's DeltaBlue in the Python
benchmark suite.
I’ve done some more work since thi

But that brings up a new question. I can create a class instance with
x = BinaryConstraint(),
That makes an instance of EqualityConstraint.
Copy/paste mistake on my part. This makes an instance of
