By default, == on your own objects only checks whether they are the very same object, not whether they hold the same values:

class Point:
    def __init__(self, x, y):
        self.x = x
        self.y = y

print(Point(1, 2) == Point(1, 2))

Define __eq__ to decide what "equal" means for your class:

class Point:
    def __init__(self, x, y):
        self.x = x
        self.y = y

    def __eq__(self, other):
        return self.x == other.x and self.y == other.y

print(Point(1, 2) == Point(1, 2))
print(Point(1, 2) == Point(2, 1))
