For the coursework, the students are required to develop an application based on detailed guidance on given specifications.  Through the coursework students should be able to: 

✔ Develop a library management system  

✔ Describe the program  ✔ Test the program with some sample data to demonstrate its behavior  ✔ Write a report to present the work 

● Students are required to submit the weekly assignments along with related evidence ● The guideline for the Documentation/Development part is given below: 

o Components to be included are cover page, and table of contents, figures  and tables, footer. 

o The report must have an Introduction section with definite goals and  objectives (approx. 400 words).  

o The report must have a Discussion and Analysis section in which  students need to explain how the program was developed.

1. Scenario 

A library maintains its book information (stock) in a text file. An application needs to  be developed which will read the text file and display all the books available for  borrowing. Then with each transaction (borrowing) a note should be generated for  the particular borrower and should be written into a file. The stock of the books should  also be updated after each transaction. For example, if the library had 10 books of  specific title, then if one of those books is borrowed then the number should change  to 9. In the case of returning a book, a note should again be generated for the person  returning the book. The stock should also be updated i.e. the quantity of the book  returned should be increased by 1. 

A sample format of the text file containing the information about the books is as  follows: 

Harry Potter,JK Rowling,30,$2 

Start With Why,Simon Sinek,10,$1.5 

Programming With Python,John Smith,20,$1.5 

*1st column contains the name of the book, 2nd column contains the name of the  author, 3rd column contains the quantity available, 4th column contains the price for  borrowing the book (for duration of 10 days) 

**You can use your own format and add other information too 

A note should be generated for each transaction. When a person borrows a book a  note should be generated which must contain the name of the borrower, the name of  the book borrowed, the date and time of such issue and the total amount to be paid  for the borrowing. If a person decides to borrow multiple books then all the borrowed  books should be written to the note and the amount should be added up for all the  borrowed books.  

When a person returns a book to the library, a note should be generated and written  to the file again. The note should contain the name of the borrower, name of the book,  date and time of the return. The lending duration should be set to 10 days, and if a  person is late in returning the book, a fine should be applied on a daily basis which  should also be present in the generated file. 

* The format of the borrowing and returning notes is up to you. But each file should  have a unique name.

2. Algorithm 

● An algorithm should be developed for the application where everything the  program does should be taken into account. The algorithm should be described  in steps, pseudocode and flowcharts should also be included. 

3. Data Structures 

● The programming should be done using data structures and operations in Python  for input/output, character and string processing, data storage.  

● It can use any primitive or complex data structures which might be necessary for  holding the data (lists, tuples, strings, dictionaries, etc.) 

● The choice of data structures must be specified in the report. 

4. Program 

● The program must work in a loop, displaying the available books and waiting for  the administrator to enter the details. The program should not close unless the  administrator decides to do so.  

● The program must check the input data, displaying error messages whenever  unwanted data is entered, for example if some string value is entered where a  numerical value is expected. 

● The program must be implemented in a modular way with separate functions for  the different operations such as user input, reading files, generating  borrowing/returning notes, etc. 

5. Description  

● The program must be described in terms of its structure and behavior.  ● It can be presented using text and structural charts, flowcharts or other diagrams  as needed. 

o The report must have a Testing section with evidence (through appropriate  screen shots) that has been carried out for the program. There should be  at least 5 various test cases following a specific testing technique.  

o The report must include a Conclusion section where they need to present  their finding of the development and research (approx. 300 words).
