Trouble understanding magic methods

Question

#i don't understand the order of operations for this example.

#in the add function, it looks like other.x value shouldn't be definded, and the self.y and other.y values aren't being used sometimes?

#which variablesgo through the init?

class Vector2D:
def __init__(self, x, y):
self.x = x
self.y = y
def __add__(self, other):
return Vector2D(self.x + other.x, self.y + other.y)

first = Vector2D(5, 7)
second = Vector2D(3, 9)
result = first + second
print(result.x)
print(result.y)

Answer 1

Not a Python expert, but __add__ means that you are overloading the "+" operator. That implies that both self and other are of class Vector2D, so they have x and y. As a result you should get 816 printed ( 5+3 7+9)

Answer 2

with result ur adding ro objects and that is wrong
and u defined a method but did not use it

Answer 3

Def __init__ initialises the object.
The __add__ defines ehat happens when you add 2 such objects.
Thus, when the code is run it executes tgis way
