Hello! It's more a design question than anything python specific. If anyone could help me, I would be grateful. If it's not the right place for this subject, please advise.
I've got a IBuyable interface. The app can sell both Products and Services (Both "Buyables"). I'm not sure if Product and Service should also be represented as interfaces (inherited from IBuyable) or if they are actually directly implementations of IBuyable. What do you think? Thanks, Marcelo.
