How To Use Classes In Python?

To create a class, use the keyword class :

  • Create a class named MyClass, with a property named x:
  • Create an object named p1, and print the value of x:
  • Create a class named Person, use the __init__() function to assign values for name and age:
  • Insert a function that prints a greeting, and execute it on the p1 object:

How do classes work in Python?

Python classes provide all the standard features of Object Oriented Programming: the class inheritance mechanism allows multiple base classes, a derived class can override any methods of its base class or classes, and a method can call the method of a base class with the same name.

What is a class in Python What is the use of a class?

A class is a user-defined blueprint or prototype from which objects are created. Classes provide a means of bundling data and functionality together. Creating a new class creates a new type of object, allowing new instances of that type to be made.

What is __ class __ in Python?
