In this manner, what is the use of __ call __ in Python?

The __call__ method enables Python programmers to write classes where the instances behave like functions. Both functions and the instances of such classes are called callables. It’s even possible to overload the “+” operator as well as all the other operators for the purposes of your own class.

Beside above, what is type () in Python?

Python | type() function. type() method returns class type of the argument(object) passed as parameter. type() function is mostly used for debugging purposes. If three arguments type(name, bases, dict) is passed, it returns a new type object.

What is __ Radd __ in Python?
