Question

Can someone help me to explain this? This is a past time question. The answer is (B), which is P == Q will evaluate as False, but I don't understand why. 

Question:

Suppose we type the following code into the Python interpreter:

>>> class Point():

...            def __init__(self, x: int, y: int):

...                  self.x = x

...                   self.y = y

...

...            def __str__(self):

...                 return '({},{})'.format(self.x, self.y)

>>> P = Point(2,3)

>>> Q = Point(2,3)

Which of the following will evaluate to False?

A.  type(P) == type(Q)

B.   P == Q

C.   P.x < Q.y

D.   str(P) == str(Q)

E.   None of the above.
