12.26 ZyProject: Irma Pince’s Library Management System
While we do our best to make our projects error-free, since we don’t reuse projects, errors can get past the review process. Please notify the staff of any errors/inconsistencies you see in the specification. We will work quickly to resolve any issues as soon as possible.
EXTRA CREDIT ADDED: for Penalty Report Function. Please see Stage4 for details.

**IF YOU ARE NOT COMPLETING THE ZYPROJECT, DO NOT SUBMIT OR TEST CODE IN THIS PROJECT **. Otherwise ZyBooks will report your score as a 0 for the project.
This ZyProject is designed to test you on everything you have learned, and designed to test all concepts you’ve learned so far.
Each succeeding stage is built upon what you have already written for the previous stage. We expect you to design, write, and test this program according to these stages—first get the first-stage program working, then modify it to satisfy the second stage, and so on. You should make sure that each stage is entirely correct and working perfectly before you go on to the next. As you complete each stage, you should check that you passed the relevant test cases before you go on to the following stage.
Development by stages is good software engineering practice. It is far better to have a program that is correct but incomplete (i.e., it doesn’t implement all the features but what it does implement is correct) than one that contains bugs.
Statement of the problem
Madam Irma Pince is the Librarian for the Hogwarts School of Witchcraft & Wizardry.
You are being asked to code a library inventory system to support the various functions/duties of the librarian.
The Hogwarts librarian has many duties, including:
Paperwork:
• Establishing library rules, regulations, policies and procedures.
• Preparing the library due date sheets and maintaining overdue records.
• Prepare and manage the library budgets, circulation files, statistics and inventories.
• Classify, and catalogue library books in order to properly making them ready for checkout.
Practical work:
• Monitoring the Library, as well as keeping it organized, clean and neat.
• Assisting students and staff members in finding the desired reading material.
• Implementing and enforcing library rules, regulations, policies and procedures.
• Placing spells on the books aimed at protecting them from mistreatment or theft.
• Checking the authenticity of the written permissions slips for the Restricted Section.
• Making sure all students have left the library by 8:00 pm, at which time the library closes.
• Overseeing the Study Hall and helping students with academic research and/or homework.
• Undertaking any other reasonable duty at the request of the Headmaster/Headmistress of Hogwarts.
Your program will keep track of the library’s inventory.
Each test case will be run with a given file. You will need to read the given file and implement the contents based on the directions given for each stage.
Technical Details
• Everything in Stage I goes into main.py
• Take a command line argument which is the filename, which is the command script, in your main statement. Do NOT take input! Read the file with the given filename.
• Create a function called hogwarts_library() which takes one input argument which is a string representing all the contents of command script.
• Process the string line-by-line (Hint: split by newline character)
• Create a variable (in modular scope) named “book_collection”, as a dictionary with the key being a string, book_title, and the value a Book nametuple instance.
• Create a function command_nb() which takes in one single line of command (a string) starting with “NB” and process accordingly
• Create a function command_li() which takes in one single line of command (a string) starting with “LI” and process accordingly
• Create a function command_db() which takes in one single line of command (a string) starting with “DB” and process accordingly
• Create a function command_fb() which takes in one single line of command (a string) starting with “FB” and process accordingly
• Create a function command_as() which takes in one single line of command (a string) starting with “AS” and process accordingly
• Create a function command_lm() which takes in one single line of command (a string) starting with “LM” and process accordingly
• Create a function command_pl() which takes in one single line of command (a string) starting with “PL” and process accordingly
• In hogwarts_library(), call one of the command_* functions whenever a newline in command script is stepped onto
• Add functions using the format/pattern above for other commands as needed in each stage
• Don’t be afraid to think outside the box.
Hints and Suggestions
It is recommended to program this assignment using debugging tools found in Python Tutor or in your favorite IDE such as OnlineGDB, IDLE, Visual Studio, PyCharm and etc. These tools help you debug and refactor your program. ZyBooks is not intended for larger scale in-browser Python development, but you of course are welcome to just use ZyBooks.
One of the early questions to ask when designing a program is what data structure(s) you should use to represent the main information in the program. Making decisions like this becomes easier with practice, but there are two things to keep in mind. First, start with the simplest data structure that does the job. (For the collection of bedrooms in this stage, maybe a list of integer room numbers is good enough, or maybe a set of room numbers.)
Second, accept that your first choice may not be your final choice; as the specifications become clearer or as circumstances change (or as you get to later stages in a problem like this one), you may decide that something else would work better.
This kind of revision is a normal part of programming. It’s no tragedy to rewrite some code in a better way, just as you should expect to revise natural-language documents. (For the books in this problem, we might decide to use a dictionary whose key is the book title and whose value is a namedtuple of book information. But we shouldn’t necessarily jump to this arrangement until we’re sure it helps us, but it isn’t a bad idea…)
Lastly, READ ALL THE WAY TO THE BOTTOM of this specification before you get started.
Don’t give up! The lab is long, but if you follow the hints, use good data structures, break things down step by step, and think ahead it is not difficult!
Stage I
For this stage, your program will keep track of the rooms that are available. This stage implements four commands, as described below. On each command line, the first two non-whitespace characters are the command; command letters may be upper or lower case.
• NB (for “Add a New Book”) followed by a comma separated list of fields: title=Title,author=Author,year_published=####,subject=Subject, section=Restricted Add a new book with the specified information. To keep the project simple, we only allow one copy of a book to present in the library.
• LI (for “List Inventory”). Print a list of all books owned/maintained by the library sorted by title.
• DB (for “Delete Book”) followed by a title=Title. Print the message, “Book Not Found. Cannot be deleted.” if the specified book isn’t present in the library. NOTE: You will update this function again in Stages II & III.
• FB (for “Find Books”) followed by 0 or more of the following search criteria: title=Title,author=Author,year_published=####,subject=Subject,section=Section. Print a list of books, sorted by title, that are owned/maintained by the library that meet the provided criteria. If 0 criteria is provided, then print all books. If no books are found matching the criteria provided, print the message, “No Books Found.”
• AS (for “Add Student”) followed by the following fields: student_name=Student Name, house_name=House. Add the student to library members. If the student is already present, print “Student Name is already present.”
• LM (for “List Members”) prints members according to each house, sorted by house and member name. If no members of a house are registered, print “No Registered Members”.
• PL (for “Print Line”), followed by any text. Simply print (or “echo”) a line, copying the input (not counting the PL and leading whitespace) to the output. You’ll find it useful in testing, and it’s also a simple way to make the program’s reports clearer or fancier.
• ** Comment, followed by any text. Like comments in a program, comment lines don’t have any effect on the program’s behavior; they just serve as annotations in the command file.
The input file may contain any number of these commands in any order. See the sample output below for the format of the printed books list.
Below is a sample command script for this stage(also in Stage1Commands.txt).

Stage II
Each stage of this assignment will continue to handle all the commands of the previous stages, of course. For this stage, your program will handle student requests, and deletions from the list of available books.
• SD (for “Start Date”) followed by a date in the following format, mm/dd/yyyy, which sets the library’s current date to the date listed. The current date will serve as the basis for reports, calculating penalties, etc…
• CB (for “Checkout Book”) followed by the following fields: title=Title, the student’s name: student_name=Student Name, then an optional number_of_days=from 1 to 14 and pass_code=PassCode for books that are Restricted. If number_of_days are not specified, then the default checkout period is 2 weeks. Your program will keep track of all the checkouts. Create a new checkout record for the specified book, and calculate a due_date.
NOTE: valid pass codes to checkout books in the Restricted section are “Accio”, and “Protego”.
• CR (for “Checkout Report”) prints all the books checked out. List checked out books with title, the name of their current borrower, and their due date. Report of books checked out needs to be organized by each school name sorted alphabetically, then each student name sorted alphabetically, and each book title sorted alphabetically. NOTE that field widths may cause book titles to be truncated in this report. Field-widths can be found in the format_string section of the file, utilities.py.
• LA (for “List Available”) print books, sorted by title, that are available to be checked out from the library inventory.
• DT (for “Due Today”) prints all the book titles & student names for books due on the current date. The report should print the the information by titles in sorted order. NOTE that field widths may cause book titles to be truncated in this report. Field-widths can be found in the format_string section of the file, utilities.py.
• AD (for “Advance Date”) advances the current library date by one day. NOTE: You will update this in Stage III.
• Update command_db() to ensure that any checkout records/information associated with a deleted book are also removed/updated.
To make your coding task easier, import the Python library datetime and use it for date calculations. It’s harder than you might think to get calculations about dates (e.g., how many days from date A to date B?) correct. The library will do it for you at the low cost of reading the documentation to see how it works. The split function with a “/” argument will be helpful, too.
Here is some sample input for this stage:

Stage III
For this stage, your program will allow library members to request holds on books that are currently checked out. The first new command for this stage adds a hold request:
• RH (for “Request Hold”) followed by the following fields: title=Title, and the student’s name: student_name=Student Name, then an optional number_of_days=from 1 to 14. If number_of_days are not specified, then the default checkout period is 2 weeks. Add a new hold record for the specified book.
Also handle these commands:
• HR (for “Hold Requests Report”). Lists all hold requests for a given book. Print sorted by title, then the student name & number of days for each request in their position of request. Print “No Holds Requested.” when there are no holds for the entire library. NOTE that field widths may cause book titles to be truncated in this report. Field-widths can be found in the format_strings section of the file, utilities.py. If any information is missing, or the book is either not present in inventory, checkout, etc, print “Invalid Hold Request for title.”
• RB (for “Return Book”), followed by the book title, title=Title. Updates checkout records & print an error message if the specified book isn’t found in inventory. An automatic checkout record should be generated for the first student who has a hold request placed for this title. If any information is missing, or the book is either not present in inventory, checkout, etc, print “Invalid Return Request for title.”
• OR (for “Overdue Report”) prints all the book titles, student names, and days past due. The report should print the information with titles in sorted order, or “No books overdue today.” when the library has no books that are overdue. NOTE that field widths may cause book titles to be truncated in this report. Field-widths can be found in the format_strings section of the file, utilities.py.
• Update command_ad() to assess house late penalties each time the current date advances.
• Update command_db() to remove any holds associated with this book when the book is deleted.
It’s a common temptation to use an elaborate test case like this one as the first test of your newly modified program. It’s all right to indulge that temptation once, if you must; of course, your test will fail. Newly modified programs always have bugs. At that point, however, you should try a succession of smaller, more circumscribed tests, rather than ramming this same large test through the program over and over again until you finally force it through successfully. It’s more productive, more thorough, and better organized in the long run to test each feature separately before going on to complex combinations. By the same token, however, adequate testing involves more than this single combination test case; this one case does not test everything that needs testing for this stage.

Stage IV
In this stage, your program will check each command for various inconsistencies and impossible situations.
First, your program should reject any checkout requests:
• for a student: ** that isn’t a library member.
• for a book: ** that has already been checked out. ** that is not present in the book collection. ** that is restricted, and a passcode has not been provided or is incorrect.
For hold requests, your program should reject hold requests that are:
• made by a student who already has a hold request
• made by a student who isn’t a registered library member
Your program must also handle deleting a book that doesn’t exist, and correctly handling penalty calculations for books that are more than 6-days over due.
PR (for “Penalty Report”) prints the point deductions for each house, sorted by house name. Then prints the penalties for individual students of that house, sorted by student name. You can assume that a student will only have one curse applied at a given time; the most severe penalty will prevail. This is an extra credit command & tested in Test Case 47.
Here is some sample input for this stage:

• UR (for “User Report”) followed by the student name, student_name=Student Name. Print the user’s curse, the books currently checked out(sorted by title) & their overdue status, followed by hold requests sorted by book title. If the user has no books checked out, print “No checkouts.”, of if the user has no books on hold, print “No holds.”
• DR (for “List All Books Due Between Two Dates”) followed by a start date & end date in the following format, start_date=mm/dd/yyyy,end_date=mm/dd/yyyy. Print the book title & student name, sorted by title, of all books due between the given dates. If none are due for the given dates or the dates are invalid, print “No books due for the given dates.”
