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.
