This can be easily done by using the pip install multipledispatch command in the command prompt. This implementation of multiple dispatch is mostly complete, performs static analysis to avoid conflicts, and provides optional namespace support. By utilizing the Type dispatch functionality, we managed to use the same name for all 3 functions, and each one's behavior is differentiated by their input type. multipledispatch supports Python 2.6+ and Python 3.2+ with a common codebase.

First, let's define 2 classes: class OneClass: def print_value(self, value): print(f'{value} - class one') class TwoClass: def print_value(self, value): print(f'{value} - class two') Then let's write some functions which will get our classes as an argument: from multipledispatch import dispatch @dispatch(OneClass, int) def test_function(obj . Types; Dispatchers; Namespaces and dispatch; Method Resolution. Multiple dispatch or multimethods is a feature of some programming languages in which a function or method can be dynamically dispatched based on the run-time (dynamic) type or, in the more general case, some other attribute of more than one of its arguments. multipledispatch is a Python library. They did this by adding a neat little decorator to the functools module called singledispatch. A summary of the changes between this version and the previous one is attached. Multiple dispatch (aka multimethods, generic functions, and function overloading) is choosing which among several function bodies to run, depending upon the arguments of a call.
