What is the purpose of magic methods whether I can do the same work by using regular codes?

Answer 1

Magic methods can be accessed by operators such as +

Instead of needing to call the method:
obj1.add(obj2)

You can simply:
obj1 = obj1 + obj2

Answer 2

It is easier to read and understand and is less verbose and doesn't populate as much the class methods.

Answer 3

I understand that.But why I need to do so as I can easily perform the same work by using structured programming?
