Please explain to me in simple terms about magic method & object oriented products. Quiet confused now.

Question

Python

Answer 1

You probably know that you can use + with type int.

5 + 3 == 8

You probably also know that you can use + with type str as well.

'5' + '3' == '53'

Different types make different use of operators or builtin functions, and 'magic methods' are special methods that define just that: The behavior of builtin python syntax for your custom-made types.

Answer 2

Thanks Honfu. Very helpful explanation

Answer 3

Magic methods are built-in function you can override.

For instance :
class A:
def __init__(self, nb) :
self.n = nb

def __add__(self, Aobj):
return self.n + Aobj.n

A1 = A(4)
A2 = A(6)
print(A1 + A2)
#outputs 10

__init__ function, like __add__ or __str__ or __getattr__ or __setattr__ are magic methods.
