init method in python 3

Question

my question is that:
Is it mandatory to always type underscore twice while writing init method(like __init__)?
Is that only the syntax?

Answer 1

It is necessary because Python treats some methods with underecores differently so there aren't name conflicts with special methods and normal ones.

Answer 2

There are special method names to define what happens when you use built-in operators or functions on your object/class, and they start and end with two underscores.

Examples:

obj1 = MyClass() __init__
obj1 + obj2 __add__
del (obj2) __del__

... and so on.
