This method is going to refer to the parent class of the child that inherits from it. What we can do to solve the problem of duplication in our child class is use the Refer to the parent class with the super() method We want to avoid unnecessary duplication. However, this defeats the purpose of setting up “legs” in the parent class in the first place. The example above will work because the child class also has the “legs” attribute. Quack." ) fluffy = Dog ( 4, True ) print ( fluffy.
Grrr." ) class Duck ( Animal ): def quack ( self ): print ( "Duck child class. tail = tail def growl ( self ): print ( "Dog child class.
Walking." ) class Dog ( Animal ): def _init_ ( self, legs, tail ): self. legs = legs def walk ( self ): print ( "Animal parent class. In Python, we need to pass the parent class as an argument to the definition of the child class.Ĭlass Animal : def _init_ ( self, legs ): self. Inheritance also provides polymorphic behavior, which can be quite powerful. We wrap common code in one class, then reuse that code in another class. Inheritance allows us to reuse code from a class. For example: a car is a vehicle, or a dog is an animal. Inheritance is usually referred to as an Is-A relationship. Inheritance allows us to define a sub or child class which inherits functionality from another class, otherwise known as a base class or a parent class.
