In one of the quiz of the Object oriented Python course we have the following code:
class Orange(Fruit):
has_pulp = True
def squeeze(self):
return has_pulp
I cannot understand why:
print(Orange().squeeze())
doesn't return True

It might return True, perhaps there's a global variable (not shown here) that was also set to True. It could just as easily have been set to False. Or perhaps it is not defined and the function will cause a NameError exception.
So since we can't say for sure that it will return True, the statement itself is then false.
