Object-Oriented Programming (OOP) Book Lending System in Python

Level 2: Intermediate

Project Level 2: Intermediate

This project is designed for intermediate learners who know Python fundamentals and are practicing building complete programs.

Project Description

For today’s project, the task is to build a console-based book lending system for a small library or a personal book collection. This app allows users to browse available books, borrow a book, return a book, and view all borrowed books.

• The user can choose option 1 to view available books for borrowing:

  

• The user can choose 2 and then enter the number of the book they want to borrow:

  

• The user can choose 3 to return a book so the book becomes available again for borrowing:

  

👉 We challenge you to use classes (i.e., OOP) instead of functions this time. Here is how the code would look like. You can complete the rest yourself.

class BookLendingSystem:
    def __init__(self):
        self.available_books = {
            1: "The Great Gatsby",
            2: "To Kill a Mockingbird",
            3: "1984",
            4: "Pride and Prejudice"
        }
        self.borrowed_books = {}

    def display_menu(self):
        print("\nWelcome to the Book Lending System!")
        ...
        ...


    def view_available_books(self):
        ...
        ...

    def borrow_book(self):
        if not self.available_books:
            ...
            ...

    def return_book(self):
        if not self.borrowed_books:
            ...
            ...

    def view_borrowed_books(self):
        if not self.borrowed_books:
            ...
            ...

    def run(self):
        while True:
            self.display_menu()
            choice = input("\nChoose an option: ").strip()
            if choice == "1":
                ...
                ...
                

system = BookLendingSystem()
system.run()

 

Learning Benefits

You will practice managing lists and dictionaries, handling user input, and implementing logical workflows for an interactive application. In addition, you will practice working with classes.
