Methods with the same name in one class in Python

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?

class MyClass:""""""    #----------------------------------------------------------------------    def __init__(self):"""Constructor"""    def my_method(self,parameter_A_that_Must_Be_String):        print parameter_A_that_Must_Be_String    def my_method(self,parameter_A_that_Must_Be_String,parameter_B_that_Must_Be_String):        print parameter_A_that_Must_Be_String        print parameter_B_that_Must_Be_String    def my_method(self,parameter_A_that_Must_Be_String,parameter_A_that_Must_Be_Int):        print parameter_A_that_Must_Be_String * parameter_A_that_Must_Be_Int
