Chapter 14, Problem 2TF

Object:

• An object is an instance of a class.
• It is a software entity.
• It contains both data and procedures.
• The data in an object is object’s data attributes.
• The object’s data attributes are the variables which reference to a data.
• The object performs a procedure which is known as methods.

Object reusability:

• Reusability means using the existing assets in some form.
• The use of object-oriented programming has been encouraged by the increased trend of object reusability.
• It is not a stand-alone program.
• Object is used by the program that requires its services.

Example program for object reusability:

#define a class

class Example_Class:

#now define a method inside the class

def my_method(self):

#print statement

print ("I am inside the method 1 of the class")

#now define a method 2 inside the class

def my_method1(self):

#print statement

print ("I am inside the method 2 of the class")

#now define a method 3 inside the class

def my_method2(self):

#print statement

print ("I am inside the method 3 of the class")

#an instance is created for the class

object = Example_Class()

#call the method inside the class using the object
