class Dog(): def __init__(self, name, owner): self.is_alive = True self.name = name self.owner = owner def eat(self, thing): print(self.name + " ate a " + str(thing) + "!") def talk(self): print(self.name + " says woof!") class Cat(): def __init__(self, name, owner, lives=9): self.is_alive = True self.name = name self.owner = owner self.lives = lives def eat(self, thing): print(self.name + " ate a " + str(thing) + "!") def talk(self): print(self.name + " says meow!")
Notice the redundancies in the code? One of the core foundations in this class is to not repeat yourself (DRY)
class Cat(Pet): # Cat inherits the Pet class - as in, all cats are pets (in this world) ...
class Pet(): def __init__(self, name, owner): self.is_alive = True # It's alive!!! self.name = name self.owner = owner def eat(self, thing): print(self.name + " ate a " + str(thing) + "!") def talk(self): print(self.name) class Dog(Pet): # Inherits all methods/variables from the Animal class def talk(self): print(self.name + ' says woof!')
super()
class Cat(Pet): # Inherits all methods/variables from the Animal class def __init__(self, name, owner, lives = 9): super().__init__(name, owner) # same as calling Pet.__init__(self, name, owner) from here self.lives = 9 def talk(self): print(self.name + ' says meow!')
