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: <your name>
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 (<your name>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.
