Methods with the same name in one class in Python

Question

How can I declare a few methods with the same name, but with different numbers of parameters or different types in one class?

What must I change in the following class?

You can try multimethods in Python:

But I don't believe multimethod is a way to go. Rather objects that you pass to a method should have common interface. You are trying to achieve method overloading similar to the one in C++, but it is very rarely required in Python. One way to do this is a cascade of ifs using isinstance, but that's ugly.
