Creating Instance Object:

Class provides the blueprints of an object so basically an object is created from class.

An object is block of memory that contains space to store all data member or instance variable.

  Creating Instance Object

To create an object the following syntax is use in python-

        Syntax ->   object_name =  Class_name (arguments)

  Example :- 

Class Demo :

        var = “hello”  # variable declaration

Obj=Demo()  # object created

                                                                                                                                                               

Here Demo is a class name . obj is an Object name.

Accessing Object Variables:-

To access the variable inside of the class use object  and  dote (.) operator . that is dote operator along with object is use to access variable .

Syntax ->

                           Object_name.Variable_name

Example –

Class Demo:

           var = “hello”

  obj.Demo()

  print(obj.var) # accessing variable and print it .

Accessing Object Functions:-

To access a function inside of an abject you use notation similar to 

accessing a variable .

Syntax ->

                           Object_name. Function_name()

Example -

Class Demo:

           X= 5

           def function(self):

                  Print(“ Welcome ”)

 obj=Demo()      # object created

  Print(obj.X)     # accessing variable and print it .

 Print(obj.function())   # accessing function and print it
