Creating Classes and Objects in Python

     Creating Classes and Objects  in Python

 

* One can create a class "Person" in which "Andy" and "Bandy" are the names of the objects within the class

 

* A Class can be created by using the keyword "class" infront of the name of the class that one is trying to make .

 

* A Class describes the attributes and actions performed by the objects of the class . Therefore , one can write the attributes ( Variables ) and actions ( Functions ) in the class as :

 ===================================================

# This is a Class with the name Person attributes means variables

  Class Person:

  name = 'Andy'

  age = 20

# actions means functions

  def talk(cls):

        print(cls.name)

        print(cls.age)

  

* One can observe from the given code that the Person Class has two variables and one function . The function that is written in the class is called a Method .

 

* If someone wants to use this Class , then one should create an Object for the class first in the given manner .

 p1 = Person()

 Here , p1 is an object of the Person Class . Object 'p1' represents memory to store the actual data . The memory needed to create object 'p1' is provided by the PVM . One may be able to observe the function / method in the class in the given manner:

 

def talk(cls):

 

Here , 'cls' represents a default parameter that indicates the class of the object . Therefore , cls.name refers to the class variable 'Andy' . One can call the "talk()" method to display the object's details as :

p1.talk()
