INFT1004/6004 - Introduction to Programming
Library Book Management System – Part 1
Introduction
This assignment involves developing a Python program to manage a library's inventory of books.
The program should utilise basic programming concepts taught in weeks 1 to 5, including
condition statements, loops, and functions . You might want to use the Math module, which is in
chapter 5 (this is optional).
Carefully read the specification below. Make sure you have all the information necessary to start
writing the program. If you are uncertain of something, do not make assumptions. Instead, post your
questions to the "assignment 1" discussion board forum and check it regularly, or ask your
demonstrators during your lab.
Note that you must complete this assignment individually. Your solution must be your own work.
You may be required to participate in an oral exam for quality assurance, consisting of an interview
with one staff and will last approximately 10 minutes. During this time, we will ask you questions
about your assignment.
Specifications
Part 1 - Define initial book inventory: When the program runs, it will first prompt the user to
define initial inventory levels for different genres of books such as Fiction, Nonfiction, Science,
and History. Each genre can hold a maximum number of books: Fiction = 30, Nonfiction = 20,
Science = 15, History = 25. The user should not be able to input an amount exceeding the
maximum.
Part 2 - Create Menu: After setting the initial inventory levels, the program will display a menu of
actions to the user. After an action is selected and executed, the menu will reappear until the user
opts to quit. If the user enters an invalid option, the program will display an error message and
request a valid input again. The menu options are:
• Action 1: Check out a book. The user will input one of the genre of the book (Fiction,
Nonfiction, Science, History) they want to borrow. The program should check if there is
inventory available for the requested genre. After book is borrowed the inventory will be
updated accordingly.
• Action 2: Return a book. The user will input the genre of the book they are returning. The
program should update the inventory accordingly.
• Action 3: Inventory analysis. The program will report (print) how many books are
available in each genre. It will also indicate if the inventory for a genre is 'high' (>= 75%
capacity), 'ok' (50-74% capacity), or 'low' (< 50% capacity).
• Action 4: Restock inventory. The user will be shown the current inventory and asked how
many books they want to add to each genre, considering the maximum limits. The
program will confirm once the inventory has been updated (if the user tries to input an
amount higher than the maximum, the program will show a message and ask again). Finally,
the function should print a message indicating that the inventory has been restocked and will
show the new amounts of genre.
• Action 5 (FOR INFT6004STUDNETS ONLY): Genre Checkout Summary -This feature will
allow the user to see how many times books from each genre were checked out. This can
help the library staff to understand which genres are currently most popular.
• Action 6: Quit. Exit the program with a farewell message.
Note that all inputs above should be positive numbers. If they are negative, the program should
show a message and ask the input again.
Program Requirements:
• A separate function should handle each part of the menu options, plus the initial
inventory definition and the menu display itself.
• Define a function called initialise_inventory() to perform the functionality ‘Define initial
inventory’. The initialise_inventory() function should ask the user the amounts to the initial
inventory levels for Fiction, Nonfiction, Science and History. The function will call another
function called check_inventory_limit() described below. The function should ask the input
again if the amounts exceed the maximum allowed, which the function below will check.
• The check_inventory_limit() function will receive as parameters the number of Fiction,
Nonfiction, Science and History input by the user. The function will check that these amounts
are less or equal to the maximum possible. The maximum possible is: Fiction = 30, Nonfiction
= 20, Science = 15, History = 25. The function check_inventory_limit() should return True (if
the amounts are less or equal to the maximum allowed) or False (if the amounts are higher
than possible).
• The main program loop will trigger define initial inventory, and then will have a loop that allows
the user to choose one of the other functionalities (i.e. display the menu). The loop should
handle an invalid input and continue running until the user chooses to quit.
Complete each function one at a time, and test the program before trying to implement a new
function.
Program Comments
At the beginning of your program you will have the following details and format as well as comments
for the program.
Author:
Date: Start date and upload date
Task: INFT1004/INFT1006 Assignment 1 Library Book Management System
Comments are expected for each block of the code about what a block of code is intended to achieve.
This will be at a function level and also for any inline code. In addition, add other comments that are
potentially important for any reader of your code.
What to submit.
You should submit the Python file called (Assign1.py) electronically via the "Assignment
1" link on Canvas. For example, your name is Abby Zammit, your file will be called
AbbyZammitAssign1.py
Handing in your work
You are to hand in the assignment electronically using Canvas’s Assignment facility. Remember, you
are to hand in your python code named correctly - (this was described under “file for submission”
above. It should be something like AbbyZammitAssign1.py (of course use your own name! )
When you are ready to submit your code file, log in to Canvas, go to the site for this course, and follow
these steps:
• Select the Modules folder.
• Click the Assignment 1 link, which will take you to the appropriate upload page.
• Click or drag the file as below. Then hit Submit Assignment.
• If you wish to see if the correct file has been uploaded then just click the download icon as below.
• If you want to submit an updated version of the assignment, go back to the Assignment link and click
Try Again.
Make sure you’re aware of the deadline: the final marking will be applied only to the most recent
submission, and if it’s submitted late it will be marked as late.
Marks will be awarded for: layout, both visual (variable names, indentation) and structural (scope of
variables, use of functions); documentation (comments); and ability of the submission to perform as
specified. A more detailed marking schema is available.
Late Penalty and adverse circumstances
Note that your mark will be reduced by 10% for each day (or part day) that the assignment is late. This
applies equally to week and weekend days. You are entitled to apply for special consideration if adverse
circumstances have had an impact on your performance in an assessment item. This includes applying
for an extension of time to complete an assessment item.
In the Canvas you will find a new forum in the discussion board: “assignment1”. Any question about
the assignment 1 you can post there. Check this forum regularly.
