Question

Using Python

You just started your summer internship with NU Bank as part of its growing development team. Your first assignment is to design and build two classes that are to be utilized in both the banks website and internal applications. The first is a loan class representing a loan contract. The second is a customer class representing the individual receiving the loan. You will be building the business logic classes, so you don’t have to worry about forms for communicating with the user or data access classes to communicate with the database. To test your classes, you will use them in a test application. The requirements for your classes and the testing application are as follows:

• You are to design and build 2 components of the Loan Processing System (LPS). There will be one class to represent loan contracts, and another to represent customers.

• Each class should have at least 2 members and 2 methods.

• The LPS will need to be able to check that the customer is at least 21 years old. A method

  (IsEligible) should return true if the customer is 21 or older and false otherwise. An associated

  method (GetAge) should return the customer’s age in years.

• When assigning the customer to the loan, the assignment should be rejected if the customer is

  ineligible based on age.

• The following pieces of information about each business object are important to track:

  o Customer:
  ▪ Customer ID, First Name, Last Name, Email, Phone, Date of Birth

  o Loan:
  ▪ Loan ID, Agent Name, Loan Amount, Interest Rate, Customer

• For purposes of testing, you will write a small application

o Gather information you need about the Customer via console input
o Any information you need about the Loan can be hard-coded using the constructor

(__init__) or properties of the class
o The application must do the following – utilizing instances of your classes:

• ▪ Ask the user for any needed information

• ▪ Allow the user to save information to the Customer object.

• ▪ Allow the user to retrieve information from the Customer object.

• ▪ Test the ‘IsEligible’ functionality and output the customer age, along with the

  loan information, if the assignment of the customer to the loan succeeds.

Answer 1

EXPLANATION:

• all of the functionalities are completed with 2 classes having remembered all the requirements.
• The function GetAge() uses datetime module of python to get the current date and then calculating the actual age of the customer.
• the IsEligible function gets the age and then verifying if customer is eligible or not.

CODE:

import datetime

class Loan:
   loans = 0
   def __init__(self,customer):
       Loan.loans +=1
       self.loanId = "L0" + str(Loan.loans)
       self.agent = "XYZ"
       self.LoanAmount = 0
       self.intRate = 10
       self.customer = customer

   def setLoanAmt(self, amount):
       self.LoanAmount = amount

   def IsEligible(self, customer):
      
       custAge = customer.GetAge()

       if custAge >= 21:
           return True

       return False

class Customer:

   def __init__(self):
       self.firstName = ""
       self.lastName = ""
       self.email = ""
       self.dob = ""

   def GetAge(self):
       if self.dob == "":
           print("Date of birth not given")
           return

       currentTime = datetime.datetime.today()

       currentYear = int(currentTime.year)
       currentMonth = int(currentTime.month)
       currentDay = int(currentTime.day)

       # customer dob
       custDay = int(self.dob[:2])
       custMonth = int(self.dob[3:5])
       custYear = int(self.dob[6:11])

      

       # getting age
       age = currentYear - custYear
       if custMonth > currentMonth:
           age -= 1
       elif custMonth == currentMonth and custDay > currentDay:
           age -= 1

       return age

if __name__ == "__main__":

   print("Welcome to the NU Bank! \nEnter your details below to apply for loan")

   customer = Customer()

   firstName = input("Enter your first name: ")
   lastName = input("Enter your last name: ")
   email = input("Enter email: ")
   dob = input("Enter Date of birth in format (dd-mm-yyyy):")

   customer.first = firstName
   customer.last = lastName
   customer.email = email
   customer.dob = dob

   age = customer.GetAge()
  

   loan = Loan(customer)

   loanAmt = int(input("Enter the amount you want in Loan: "))
   loan.setLoanAmt(loanAmt)

   if loan.IsEligible(customer):
       print("Congratulations! Your loan has been sanctioned")
       print("Your age is eligible for this loan , your age is: ", age)
       print("Your loan ID:", loan.loanId)
       print("Your loan agent: ", loan.agent)
       print("Your loan amount: ", loan.LoanAmount)
       print("Interest Rate: ", loan.intRate)
   else:
       print("Sorry your age is below eligibility criteria")
       print("Your age is:", age)
