I’m not sure that’s possible, and I’m wondering if that’s the way to go, or if there exists a better way of doing that.

I’ll create a toy example to expose what I’m looking for.

Suppose I have people of different nationalities. I’m creating a class for each nationality and this classes all have a method greeting.

class French:
  def greeting(self):
    print("Bonjour")

class English:
  def greeting(self):
    print("Hello")

class Spanish:
  def greeting(self):
    print("Hola")

Of course this could be done having a single class Person and using conditionals inside the method greeting, but we can imagine the function greeting being more complex than that and justifying having a class for each Nationality.

You could also imagine all this Nationalities being in reality a child class of a class Person and overriding the method greeting to output their own language.

Now, imagine I another feature, like “Sport” which then I also create different classes for the different sports.

class Football:
  def sport(self):
    print("Football")

class Tennis:
  def sport(self):
    print("Tennis")

class Golf:
  def sport(self):
    print("Golf")

Again, instead of having a single class Sport, imagine the function sport is more complex, and different classes are justified. And again we can imagine all this sports being children of a class Sport and overriding the method sport.

Now, I want a class that inherits both from a Nationality and a Sport.

So I can create a class FrenchFootball with inherits both from French and Football.

class FrenchFootball(French, Football):
  pass

I can now instantiate this class and it will have both a method greeting and a method sport

foo = FrenchFootball()
foo.greeting()   # Bonjour
foo.sport()      # Football

Now, here’s the question:

The child class, doesn’t need to add any attributes or methods, it just links a Nationality with a Sport so the resulting instance says Bonjour and likes Football.

However, in order to create such an instance, I have to define a class FrenchFootball that just inherits both classes.

If I want all combinations of this toy example I need to define 9 child classes, so I can instantiate them.

Question:

Is there a way I can instantiate foo to be an English Tennis without having to code a class EnglishTennis?

You can imagine that having 10 sports and 20 Nationalities makes creating those child link classes a nightmare.
