These so-called "magic methods" have actually nothing to do with wizardry, lol.
Okay, they're just special methods with special kind of names.
Like, __init__ is a magic method and since it has double underscores on the both side, they're also called dunders. They comes to handy when you need to overload basic functionalities according to your object.
You might have seen in Python, using '+' in between two numbers results in returning a third number which is obv. the sum of two but when you use the same '+' between two strings, it concatenates them! ...ever wondered why?
It's bcz functionality of '+' can be altered by overloading __add__ magic method and so it's been overloaded so for string objects.
There are many "magic methods" available including
__init__
__add__
__sub__
__mul__
__floordiv__
__truediv__
__mod__
__and__
__or__
__eq__
__neq__
And many more
