Dynamic inheritance in Python

Question

Say I have 2 different implementations of a class

class ParentA:
    def initialize(self):
        pass

    def some_event(self):
        pass

    def order(self, value):
        # handle order in some way for Parent A


class ParentB:
    def initialize(self):
        pass

    def some_event(self):
        pass

    def order(self, value):
        # handle order in another for Parent B

How can I dynamically let some 3rd class inherit from either ParentA or ParentB based on something like this?

class MyCode:
    def initialize(self):
        self.initial_value = 1

    def some_event(self):
        # handle event
        order(self.initial_value)


# let MyCode inherit from ParentA and run
run(my_code, ParentA)

Answer 1

Simply store the class-object in a variable (in the example below, it is named base), and use the variable in the base-class-spec of your class statement.

def get_my_code(base):

    class MyCode(base):
        def initialize(self):
          ...

    return MyCode

my_code = get_my_code(ParentA)
