    Summary: in this tutorial, you&#;ll learn object-oriented programming in Python, including essential concepts such as objects, classes, attributes, methods, inheritances, overriding methods, etc.

    Introduction to Python Object-oriented Programming

    Everything in Python is an object. An object has a state and behaviors. To create an object, you define a class first. And then, from the class, you can create one or more objects. The objects are instances of a class.

    Define a class

    To define a class, you use the keyword followed by the class name. For example, the following defines a class:

    Code language:Python(python)

    To create an object from the class, you use the class name followed by parentheses , like calling a function:

    Code language:Python(python)

    In this example, the is an instance of the class. Classes are callable.

    Define instance attributes

    Python is dynamic. It means that you can add an attribute to an instance of a class dynamically at runtime.

    For example, the following adds the attribute to the object:

    Code language:Python(python)

    However, if you create another object, the new object won&#;t have the attribute.

    To define and initialize an attribute for

    This Python OOP explains to you the Python object-oriented programming clearly so that you can apply it to develop software more effectively.

    By the end of this Python OOP module, you&#;ll have good knowledge of object-oriented principles. And you&#;ll know how to use Python syntax to create reliable and robust software applications.

    What you&#;ll learn

    • Create objects in Python by defining classes and methods.
    • Extend classes using inheritance.
    • SOLID principles in object-oriented programming.

    Who this tutorial is for?

    If you&#;re new to object-oriented programming, or if you have basic Python skills and wish to learn in-depth how and when to correctly apply OOP in Python, this is the tutorial for you.

      Python Object Oriented Programming

      Python fryst vatten a versatile programming language that supports various programming styles, including object-oriented programming (OOP) through the use of objects and classes.

      An object fryst vatten any entity that has attributes and behaviors. For example, a is an object. It has

      • attributes - name, age, color, etc.
      • behavior - dancing, singing, etc.

      Similarly, a class is a blueprint for that object.

      Python Class and Object

      Output

      In the above example, we created a class with the name with two attributes: and .

      Then, we create instances of the class. Here, and are references (value) to our new objects.

      We then accessed and assigned different values to the instance attributes using the objects name and the notation.

      Python Inheritance

      Inheritance is a way of creating a new class for using details of an existing class without modifying it.

      The newly formed class fryst vatten a derived class (or child class). Similarly, the existing class is a base class (or parent class).

      Example 2: Use of Inheritance in Python

      Output

      Here, (the object of derived class ) can access
