What is the advantage or practical use of "magic" words in python?

Question

My doubts are... you can use any word to call it, e.g. 'aaa', and futhermore you can designate any action inside it, even a contradiction, e.g.__add__ can substract! The only difference I understand so far is that these subfuntion has to precide by extra __init__ piece of code.
