Question

I need help constructing a special inventory system. I need certain components that will check the age of the customer and then assign them to a car model.

It will be business logic classes. To test your classes, you will use them in a relatively small test application.

The requirements for testing and the classes within PYTHON 3 are as follows:

• Need to build and design TWO components of the reservation sys.

One class to represent customers, and another to represent vehicles with AT LEAST 2 METHODS IN EACH OF THE TWO CLASSES.

Again, the reservation system will also need to verify if the customer is at least twenty-five years of age, if they are of age the process can continue and car assigned.. Otherwise, the user should be notified that they are not allowed to rent the car with a prompt stating sorry they are under twenty-five years of age.

• If the customer is 25+, the components should assign the client a car

• The following will each need to be inputted in each of the two classes:  

For the customer class: CustomerID, Name, DOB (to determine eligibility), phone number, and vehicle assigned.

For the vehicle class:  VIN Number, Make, Model, and model year.

I just need a small application for testing purposes. The console input should be used to GATHER ALL INFORMATION about customer data.

The information you need about the vehicle can be hard coded with the init constructor or you can also set methods of the Vehicle class.

When complete the small application should include the following – adaptation with instances of your classes,  Asking the user for all the required information, while confirming if the user meets the 25+ requirement.

If this age requirement is met the client is assigned a vehicle.

There should be an OUTPUT VEHICLE confirmation to the screen, showing: CustomerID, Name, Vehicle VIN, Make, and the Model assigned..

That is all!

Answer 1

Short Summary:

·       Created Customer and Vehicle class.

·       Used __str__ methods to print the details

·       Constructor of Customer class assigns a vehicle, if customer age is 25+.

·       Hard coded the vehicle information in the constructor of Vehicle class.

Source Code:

from datetime import datetime

#Customer class

class Customer:

    #constructor

   def __init__(self, id, name, dob, phone):

      self.__id = id

      self.__name = name

      # Convert the string into datetime

      self.__dob = datetime.strptime(dob, '%m/%d/%Y')

      self.__phone = phone

     

      # if age is 25+, assign a vehicle

      if self.__getAge() > 25:

        self.__vehicle = Vehicle()

      else:

        self.__vehicle = None

       

    #Override tostring method to return the attributes values

   def __str__(self):

       # if vehicle is assigned

       if self.__vehicle is not None:

           return ("Customer ID: " + str(self.__id) + "\nCustomer Name: " + self.__name + "\nVehicle: " + str(self.__vehicle))

       else:

           return ("Customer ID: " + str(self.__id) + "\nCustomer Name: " + self.__name + "\nVehicle: "

                   + "Sorry you are under 25; not allowed to rent a car")

  

   # private method to calculate age

   def __getAge(self):

        today = datetime.today()

        return int((today - self.__dob).days / 365.25);

          

#Vehicle class

class Vehicle:

    #constructor

   def __init__(self):

      self.__vin = 12345678

      self.__make = "Honda"

      self.__model = "Civic"

      self.__year = 2018

   

    #Override tostring method to return the attributes values

   def __str__(self):

       return ("Vin number: " + str(self.__vin) + ", Make: " + str(self.__make) + ", Model: "

               + str(self.__model) + ", Year: " + str(self.__year))

   

# Main method gets user inputs and does the reservation

def doReservation():

    custId = input("Enter customer id: ")

    name = input("Enter customer name: ")

    dob = input("Enter customer date of birth(MM/DD/YYYY): ")

    phone = input("Enter customer phone number: ")

   

    # Create customer class

    customer = Customer(custId, name, dob, phone)

    print("Reservation Result: ")

    # print the information

    print(customer)

if __name__ == "__main__":

    # Call main method to start the program

    doReservation()

Sample Run 1:

Shell Python 3.7.6 (bundled) >>> %Run Reservation.py Enter customer id: 100 Enter customer name: SaraDurs Enter customer date of birth (MM/DD/YYYY): 12/31/1989 Enter customer phone number: 123 456 7890 Reservation Result: Customer ID: 100 Customer Name: SaraDurs Vehicle: Vin number: 12345678, Make: Honda, Model: Civic, Year: 2018

Sample Run 2:

Shell >>> %Run Reservation.py Enter customer id: 101 Enter customer name: Kevin Enter customer date of birth (MM/DD/YYYY): 8/26/2010 Enter customer phone number: 123 456 Reservation Result: Customer ID: 101 Customer Name: Kevin Vehicle: Sorry you are under 25; not allowed to rent a car >>>
