EncapsulationĮncapsulation is also an essential aspect of object-oriented programming. So, the abstract "animal" concept does not actually "speak", but specific animals (like dogs and cats) have a concrete implementation of the action "speak". Here, the "speak" behavior is polymorphic in a sense and depends on the animal. For example - you have a class animal, and all animals speak. By polymorphism, we understand that one task can be performed in different ways. Polymorphism contains two words "poly" and "morphs". It provides the re-usability of the code. The new class is known as a derived class or child class, and the one whose properties are acquired is known as a base class or parent class. It specifies that the child object acquires all the properties and behaviors of the parent object.īy using inheritance, we can create a class which uses all the properties and behavior of another class. Inheritance is the most important aspect of object-oriented programming, which simulates the real-world concept of inheritance. In Python, a method is not unique to class instances. The method is a function that is associated with an object. We will learn more about class and object in the next tutorial. The c1 object will allocate memory for these values. We have created a c1 object to access the class attribute. In the above example, we have created the class named car, and it has two attributes modelname and year.
