You didn't mention which question you are asking about, but the one that gives most folks trouble has a class method that ends with "return has_pulp".

This example is missing the "self." prefix before the name, which is needed to reference an instance variable.

its this:

class Orange(Fruit):
    has_pulp = True

    def squeeze(self):
        return has_pulp

Orange().squeeze() will return True. (So how should it be entered to return true?)

Yes, that's the one. The last line is the problem, fixing it (which would make the question True) would look like:

        return self.has_pulp
