As a former student of accounting this sounds rather interesting.

If I had to take a wild guess, I assume these two lines are located
inside an instance method of the Record class, correct?

The program does not automatically create an instance of Record when
you say "weath_account.add_record(self)". At this point the instance
of the record has to have already been constructed, if you're
referencing it with self.
This is very confusing, maybe you could try and clarify the situation
a bit more? The more code you can post the better...
