Book Tracker Program Demonstration | Rishi Nalem

Introduction

This article will guide you through a demonstration of a simple book tracking program. This program will allow you to keep track of your reading list, mark books as read, and even rate them. It's a practical example of how to apply programming concepts like data structures, loops, and user input to create a useful application. We will be using Python for this demonstration. You can find the complete code on GitHub:

Understanding such programs helps in grasping basic programming concepts and can even serve as a starting point for building more elaborate personal projects.

Program Structure

Let's break down the core components of our book tracker program:

Data Structure:

We'll use a Python dictionary to store book information. Each book will be represented as a dictionary within the main dictionary, with keys like 'title', 'author', 'genre', 'read', and 'rating'.


books = {
"book1": {
    "title": "The Hitchhiker's Guide to the Galaxy",
    "author": "Douglas Adams",
    "genre": "Science Fiction",
    "read": False,
    "rating": 0
},
"book2": {
    # More books here...
}
}

Menu-Driven Interaction:

A simple menu will guide the user through the program's functionalities. Users can choose to add books, view their reading list, mark books as read, and rate books.


while True:
print("\nBook Tracker Menu:")
print("1. Add Book")
print("2. View Reading List")
print("3. Mark Book as Read")
print("4. Rate Book")
print("5. Exit")

choice = input("Enter your choice (1-5): ")

# Process user choice...

Functions for Different Operations:

We'll create functions to handle each menu option. For instance, a 'add_book' function will prompt the user for book details and add it to the 'books' dictionary.


def add_book():
title = input("Enter book title: ")
author = input("Enter author: ")
genre = input("Enter genre: ")
books[f"book{len(books)+1}"] = {
    "title": title,
    "author": author,
    "genre": genre,
    "read": False,
    "rating": 0
}
print("Book added successfully!")

Code Implementation

Here's the complete Python code for our book tracker program:



books = {}

def add_book():
title = input("Enter book title: ")
author = input("Enter author: ")
genre = input("Enter genre: ")
books[f"book{len(books)+1}"] = {
"title": title,
"author": author,
"genre": genre,
"read": False,
"rating": 0
}
print("Book added successfully!")

def view_reading_list():
if not books:
print("Your reading list is empty.")
return
print("\nReading List:")
for book_id, book_data in books.items():
print(f" {book_id}: {book_data['title']} by {book_data['author']} ({book_data['genre']})")
if book_data['read']:
print(f" Status: Read, Rating: {book_data['rating']}/5")
else:
print(" Status: Not Read")

def mark_as_read():
view_reading_list()
if not books:
return
book_id = input("\nEnter the ID of the book to mark as read: ")
if book_id in books:
books[book_id]['read'] = True
print("Book marked as read!")
else:
print("Invalid book ID.")

def rate_book():
view_reading_list()
if not books:
return
book_id = input("\nEnter the ID of the book to rate: ")
if book_id in books:
rating = int(input("Enter rating (1-5): "))
if 1 <= rating <= 5:
books[book_id]['rating'] = rating
print("Book rated successfully!")
else:
print("Invalid rating. Please enter a value between 1 and 5.")
else:
print("Invalid book ID.")

while True:
print("\nBook Tracker Menu:")
print("1. Add Book")
print("2. View Reading List")
print("3. Mark Book as Read")
print("4. Rate Book")
print("5. Exit")

choice = input("Enter your choice (1-5): ")

if choice == '1':
    add_book()
elif choice == '2':
    view_reading_list()
elif choice == '3':
    mark_as_read()
elif choice == '4':
    rate_book()
elif choice == '5':
    print("Exiting Book Tracker. Goodbye!")
    break
else:
    print("Invalid choice. Please try again.")

Explanation

Initialization:
- The books dictionary is initialized to an empty dictionary.
- add_book Function:
- Takes user input for the book's title, author, and genre.
- Creates a new dictionary for the book, sets its initial read status to False, and its rating to 0.
- Adds this book dictionary to the books dictionary using a unique key generated from the number of existing books.
- view_reading_list Function:
- If the books dictionary is empty, it prints a message indicating an empty reading list.
- Otherwise, it iterates through the books dictionary and prints information for each book, including its ID, title, author, genre, and its read status and rating if applicable.
- mark_as_read Function:
- Displays the reading list.
- Prompts the user to enter the ID of the book they want to mark as read.
- Updates the read status of the corresponding book in the books dictionary to True.
- rate_book Function:
- Displays the reading list.
- Prompts the user to enter the ID of the book they want to rate.
- Takes user input for the rating (between 1 and 5) and updates the rating in the corresponding book's dictionary.
- Main Loop:
- Continuously presents the menu options to the user.
- Takes the user's choice and calls the appropriate function based on their input.
- If the user chooses to exit (option 5), the loop breaks.
  Running the Program
Save the Code: Save the code as a .py file (e.g., book_tracker.py).
1. Run the Script: Open a terminal or command prompt, navigate to the directory where you saved the file, and run the script using python book_tracker.py.
2. Interact with the Menu: Follow the menu prompts to add books, view your list, mark books as read, and rate them.
  Further Enhancements
  This is a basic book tracker. You can extend its functionality by:

Saving Data: Implement saving the book data to a file so that it persists between program runs.
Search Functionality: Add the ability to search for books based on title, author, or genre.
Sorting Options: Allow users to sort the reading list by different criteria (title, author, genre, rating, etc.).
User Interface: Use a graphical user interface (GUI) library like Tkinter or PyQt for a more visually appealing experience.
Conclusion
This demonstration provides a basic understanding of how to create a book tracker program using Python. By understanding the core concepts like data structures, loops, and user input, you can build more complex and customized applications. Remember, programming is about problem-solving, and this book tracker example serves as a stepping stone towards building your own unique projects.
