why will this return false?

231,268 PointsI'll guess you are asking about the question that shows this code:
class Orange(Fruit):
has_pulp = True
def squeeze(self):
return has_pulp
And then says "Orange().squeeze()
will return True
."
The issue here is that since the "squeeze" method returns "has_pulp" 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.

" by itself should return a new instance.
