Inheritance in Python
Inheritance is used to inherit another class' members, including fields and methods. A sub class extends a super class' members.
class SubClass(BaseClass): def some_method(self, passed_params): #calling base class version of method BaseClass.some_method(self, passed_params)
Sub classes inherit methods and members from the base class. If a subclass has a method with the same name as the base class, the subclass' method overrides the base class method.
class Cat(object): def __init__(self, name): self.name = "Garfield" def sound(self): return "Meow" class Tiger(Cat): def __init__(self, name): #will overwrite Cat constructor self.name = "Mike Tyson Jr." def sound(self): #will overwrite the Cat sound method return "Roar" def cat_sound(): Cat.sound() #will call cat's sound
