Library management system

A-simple-Library-Management-system-using-Python

Libraries used: Pandas and Datetime.

This program uses a CSV file as the database to handle the list of books and their borrower/due date/availability details. The Terminal is used to operate the program and doesn't use a GUI.

This is a simple library management system that an admin can operate to
-> view the list of books and their availability
-> lend books
-> return books
-> view the list of books borrowed by a certain student (while returning a book)
-> automatically calculate the FINE to be paid for late return of book beyond the due date.

-> errors such as lending a book which isn't available, trying to return a book which isn't borrowed by that student are also handled.
-> new books can be added to the database by directly editing the CSV file.

Instructions to run the program:

Put both the main_lms.py and Book_list.csv file in a single folder and run the python file using command "python main_lms.py".

9. Requirements:

• Python 3.x
• pandas library (install using 'pip install pandas')

2. Installation:

• Ensure that Python is installed on your system.
• Install the pandas library by running 'pip install pandas' in your terminal.

3. Usage:

3.1. Running the System:

• Place the 'Book_list.csv' file in the same directory as this script. This CSV file stores book data.
• Run the script in your terminal: $ python library_management.py

3.2. Main Menu Options:

• Enter one of the following menu options (1 to 5) to perform actions:

  1. Display all books in the library.
  2. Display available books.
  3. Borrow a book.
  4. Return a book.
  5. Quit the system.

• Follow on-screen prompts for each option:

  • Enter the appropriate information when prompted, such as borrower IDs and book codes.
  • The system will provide feedback, update the book database, and calculate fines for late returns.

4. Data Storage:

• The system uses a CSV file ('Book_list.csv') to store and manage book data. The CSV file includes the following columns:
  • TITLE: Book titles.
  • Book Code: Unique book identifiers.
  • Status: Book availability (AVAILABLE or BORROWED).
  • Borrower ID: Borrower identification (empty for available books).
  • Due Date: Date by which borrowed books should be returned (empty for available books).

5. Customization:

• You can customize the following constants in the code to tailor the system to your needs:
  • FINE_PER_DAY: Defines the fine rate per day for late returns (default: 1).
  • BORROW_PERIOD: Specifies the default borrowing period in days (default: 15).

6. Error Handling:

• The system handles common errors, but user inputs should be valid to prevent unexpected behavior.
• Enhance error handling and validation as needed for your specific requirements.

7. Notes:

• Borrowers can borrow multiple books, but they must return them within the specified due date to avoid fines.
• The system enforces borrowing limits for each borrower.
