Submitted by Shivang Yadav, on February 15, 2021

Problem Statement: We need to create instances of an object using a constructor.

Problem Description: We will use Person class and create the instance of it using a constructor. Then accept the person’s information and print their details.

Algorithm:

• Step 1: Create a class named Person to store information of person (name and age).
• Step 2: Create the object of class and then input the information using getPersonDetails() method.
• Step 3: Then we will print the information using printDetails() method.

Program to illustrate the constructor initialization

class Person:
    def __init__(self):
        print("Person Created[instantiate]")
    def getPersonDetails(self):
        self.name = input("Enter Name : ")
        self.age = int(input("Enter Age : "))
    def printDetails(self):
        print(self.name,self.age)

P1=Person()
P2=Person()
P1.getPersonDetails()
P2.getPersonDetails()
print("Printing details of the person...")
P1.printDetails()
P2.printDetails()

Output:

Person Created[instantiate]
Person Created[instantiate]
Enter Name : John
Enter Age : 34
Enter Name : Jane 
Enter Age : 32
Printing details of the person...
John 34
Jane  32
