Dunders and Magic Methods - "other"?

Question

In the coded example I am given in, it reads:

def __add__ (self, other):

Does the other "self" NEED to be called "other" or not? Thanks 🙂

Answer 1

Neither of them NEED to be called that, it just really helps when writing code and its standard.

For example think of a point. A tuple with an x and y coordinate. Theres not a good way to add them in python, but what if we made a "Point" class and overloaded the + opoerator?

...
...
def __add__(self, other):
p3 = Point(self.x + other.x, self.y + other.y)

Answer 2

I really didn't get what you mean so here is a simple code of adding two numbers

class adding():
def __init__(self,x, y):
self.x=x
self.y=y
def __add__(self,second):
return self.x+second.x

a=adding(5,6)
b=adding(6,7)
print(a+b)

Answer 3

Thanks for the answers!
