Assignment : Implementing a Library Management System

[Pankaj-Str]

Objective:
The purpose of this assignment is to practice the concepts of Object-Oriented Programming (OOP) in Python by implementing a simple Library Management System.

Instructions:

1. Class Definitions:

   • Create a class Book with the following attributes:

     • title: A string representing the title of the book.
     • author: A string representing the author of the book.
     • isbn: A string representing the ISBN number of the book.
     • available: A boolean indicating whether the book is available for borrowing (default is True).

   • Create a class Member with the following attributes:

     • name: A string representing the name of the member.
     • member_id: An integer representing the unique ID of the member.
     • borrowed_books: A list to keep track of books borrowed by the member (initially empty).

   • Create a class Library with the following attributes and methods:

     • books: A list to store all the books available in the library.

     • members: A list to store all the members of the library.

     • Methods:

       • add_book(book): Adds a Book object to the library.
       • remove_book(isbn): Removes a book from the library based on its ISBN.
       • register_member(member): Registers a new Member to the library.
       • borrow_book(member_id, isbn): Allows a member to borrow a book if it is available.
       • return_book(member_id, isbn): Allows a member to return a borrowed book.
       • list_available_books(): Lists all available books in the library.
       • list_borrowed_books(member_id): Lists all books borrowed by a specific member.

2. Implementation:

   • Implement the classes and methods as described.
   • Handle edge cases such as attempting to borrow a book that is not available, returning a book that was not borrowed, etc.

3. Testing:

   • Create instances of Book and Member.
   • Test the functionality of the Library class by adding books, registering members, borrowing and returning books.
   • Ensure that the list of available books updates correctly after borrowing and returning.

Example:

# Create books
book1 = Book("The Alchemist", "Paulo Coelho", "978-0061122415")
book2 = Book("To Kill a Mockingbird", "Harper Lee", "978-0060935467")

# Create members
member1 = Member("Rajesh Kumar", 1)
member2 = Member("Sita Sharma", 2)

# Create a library
library = Library()

# Add books to the library
library.add_book(book1)
library.add_book(book2)

# Register members
library.register_member(member1)
library.register_member(member2)

# Borrow a book
library.borrow_book(1, "978-0061122415")

# List available books
library.list_available_books()

# Return a book
library.return_book(1, "978-0061122415")

# List borrowed books for a member
library.list_borrowed_books(1)

Submission:

• Submit the Python code file (.py) containing the implementation of the classes and a main function that tests the functionality.
• Include comments explaining your code and the logic behind your implementation.

Bonus:

• Extend the Library class to handle late returns by implementing a method calculate_fine(member_id, days_late) that calculates a fine based on the number of days a book is returned late.

This assignment will help reinforce the principles of OOP in Python, including class design, inheritance, and method implementation.

Hello sir, I have implemented this library application portal in a slightly different way as you specified in the question / issue. However, along with the functions you specified in the question, I have included other functions also in the program to perform other tasks that are commonly performed in a library management application. Here is the link where you can find the code on my git profile.
