STOP!

This chapter $[$Wk $4($Python$)-$ Project Programming Milestone $2($User objects$)]$ starting with section $9\mathrm{.}1$ Wk $4$ Milestone $2($Part$1-$ User objects$)$ is for students completing the Python path of this capstone project.

If you are following the Java path for the capstone project, please navigate back to Blackboard and find the link to Wk $4($Java$)-$ Project Programming Milestone $2($User objects$).$ You can also navigate within the zyBook to Chapter $10,$ section $10\mathrm{.}1$ to complete your graded work for week $4.$

Vendor truck ordering application is a capstone project that allows a food truck company to maintain a food and user database as well as enable customers to place orders.

This project is divided into $3$ milestones: $1)$ Database setup, $2)$ User object implementations with database access, and $3)$ Final system integration.

Milestone $2$ consists of $3$ labs. In this lab, three user classes are defined: a User base class, an Admin class that extends User, and a Customer class that extends User.

Follow the specifications listed below to complete Users.py$.$

User is the base class for Admin and Customer classes with the following specifications:

Attributes

user$\_$name $($string type$)-$ username of user

account $($string type$)-$ account type of user $($admin or customer$)$

first$\_$name $($string type$)-$ first name of user

last$\_$name $($string type$)-$ last name of user

email $($string type$)-$ email address of user

phone$\_$num $($string type$)-$ phone number of user

password $($string type$)-$ password of user

Instance method

$\_\_$init$\_\_($user$\_$name, account, first$\_$name, last$\_$name, email, phone$\_$num, password$)$

An overloaded constructor that instantiates a User object with the parameters.

Admin is a class that extends User class. Admin objects are used to describe users with admin account type and has the following specifications:

Attributes

employ$\_$Id $($string type$)-$ employee ID of admin user

Instance methods

$\_\_$init$\_\_($user$\_$name, account, first$\_$name, last$\_$name, email, phone$\_$num, password, id$)$

An overloaded constructor that instantiates a Admin object with the parameters.

$\_\_$str$\_\_()$

Return a string representation of Admin object.

Ex: for an Admin object with user$\_$name, first$\_$name, last$\_$name, and employ$\_$Id$,$ the $\_\_$str$\_\_()$ method returns

first$\_$name last$\_$name: user$\_$name, Employee ID: employ$\_$Id

Customer is a class that extends User class. Customer objects are used to describe users with customer account type and has the following specifications:

Attributes

card$\_$num $($string type$)-$ credit card number of the customer

card$\_$date $($string type$)-$ expiration date of credit card

address $($string type$)-$ billing address of the customer

points $($int type$)-$ reward points the customer has accumulated

history $($int type$)-$ receipt number of the customer's last order

Instance methods

$\_\_$init$\_\_($user$\_$name, account, first$\_$name, last$\_$name $,$ email, phone$\_$num, password, card$\_$num, card$\_$date, address, points, history$)$

An overloaded constructor that instantiates a Customer object with the parameters.

Set user$\_$name to "Guest" and other attributes to $""$ or $0$ as default values if no parameter is entered.

$\_\_$str$\_\_()$

Return a string representation of Admin object.

Ex: for a Customer object with user$\_$name, first$\_$name, last$\_$name, and points, the $\_\_$str$\_\_()$ method returns

first$\_$name last$\_$name: user$\_$name, Rewards: points

This lab does not use DbManager.py; therefore do not use the FoodVendar.py from Milestone $1.$ Modify the main method in FoodVendor.py provided in this lab to test the new user classes. See examples in the template file.
