Introduction

Managing books and borrowers is a core part of any library system. While many modern solutions use databases and web interfaces, I decided to start simple and build my own file based library management system using Python.

This is my first step toward real-world software development, focusing on logic, user input, and file handling.

Features

Here's what my library system can currently do:

Add or remove books (fiction and nonfiction)
Add or remove borrowers
Track which borrower took which book
Classify and view books and borrowers by category
Use persistent storage via .pkl files (Pickle module)

Tech Stack

Python
pickle for data storage (instead of SQL)
File system used for saving lists of books and borrowers

How It Works

1. Mode Selection

Users start by choosing one of the two modes:

Enter or remove books/borrowers
Classification

2. Book Management

Under the first mode, you can:

Add books (fiction or nonfiction)
Remove books (with title input)

3. Borrower Handling

The program allows:

Assigning a book to a borrower
Removing a borrower-book record
Viewing all current borrower entries

4. Classification

You can classify entries as:

Fiction / Nonfiction
Books / Borrowers

For Example

pythonCopyEditwith open("libruary software/fiction.pkl", "rb") as fr:
    f = pickle.load(fr)
    f.append(input("book: "))

This adds a book to the fiction category and stores it in a file.

Lessons Learned

Basic I/O operations
File handling and error management
How to structure if-else logic cleanly
Importance of error handling (e.g., file not found, invalid input)

Conclusion

This was a small but exciting project that helped me solidify my Python fundamentals and understand how software can interact with files.
