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

" and not "self.has_pulp
" we don't have any information to really know what it will return. 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.
