Who can explain in simple terms what "__" means for python?

Question

Python

I constantly meet in classes __init__(). I plunged into the documentation, but due to my lack of knowledge of English, I did not really understand this magic. Please explain in simple terms.

Answer 1

What is the meaning of single and double underscores...

Answer 2

Just the name of the method. The presence of "__" does not give any special properties (I cannot but mention name mangling , although in this case it has nothing to do with it).
Objects in python have a number of special methods (more precisely, property names) that will be called in certain cases of using the object (if, of course, such properties are defined).
__init__called after object creation, usually used to initialize it. And, for example, __str__when converting an object to a string (for example, str(obj)).
