Library Management System Project in Python

What We are Building?

With the below article we are planning to build the library management system project in Python which can be implemented in schools, libraries, or even colleges where we need to keep a dynamic track of the books present. The source code that we shall be used for the Library management system project in Python can be implemented for anything and everything to do with book publication. We shall be building a library y management systeprojectsct in Python as we get the ease to find the syntax emphasizing readability along with reducing time when incorporating the code in development. The data storage will be handled by MySQL Database as it can store and handle different tables.

We created this project with the object being it becomes very tedious and time-taking if manually all the n number of books need to be tracked in a library. To reduce the pain points of the library owner and take the help of technology and ease the process, we are building this project.

Pre-Requisites

The pre-requisites that must be refreshed before we jump on to building our Library management system project in Python which shall also help us understand the code snippets better are as follows:

• Basics of Python
• For loop in Python
• While looping in Python
• User-defined function in Python
• CRUD in SQL
• Select SQL
• Insert in SQL

How are We Going to Make a Library Management System?

The algorithm that we shall be following to build the Library management system project in Python is as below:

• We start the Library management system project in Python by creating the user-defined function as the main menu function that will allow the user of the project to explore the different features that we add to the Library management system project in Python.
• Then, we proceed to create the Add Books features to add the books in the Library management system project in Python where we can store details related to books like Publisher, Author, Number of books, Title, and Price.
• We need to create the UDF for Add Member to allow the user of the project to add the member details in the Library management system project in Python.
• We also create the UDF (user-defined function) for Updating the Books and Members that will help the user of the Library management system project in Python to update the details associated with any member or the books.
• As it's important to keep a track of the book details to manage the whole Library management system project in Python we will create the UDF for Issuing the Book
• Our use case also solves the problem related to returning the books hence we need to create a UDF in Python that will check if any book has exceeded its date of return and fine needs to be charged.
• To return an Issue Book, it's important to search for that book first, and hence we will be doing so with this step to create a UDF for Search Menu.
• To let the user of the project keep a track of their fines, book issues, adding new books and members, and other related costs, we will create a UDF named Report menu to generate reports and let the user analyze them without wasting any manual effort to create the report.
• Lastly, we will also add the Special Menu UDF that will capture any special requirements the user of the Library management system project in Python has.

Final Output

The final project shall look like this where we can see the Library management system project in Python after execution.

The three tables: library_book, library_member, and library_trans are as below respectively.

Requirements

The important libraries, modules, and other Python packages that are required to create the Library management system project in Python are as follows:

• MySql Connector: Module that is used to create a connection to the database to fetch or add data in the database and tables created under.

• DateTime: Using the below-given syntax you can import the DateTime which can be used to set up the date and fetch the current date which can then be used to update the details on the tables of the databases.

Creating Library Management System Project Using Python

Now as we have understood the different libraries, modules, and other prerequisites that must be downloaded beforehand along with the algorithm that we shall be taking into consideration while building the Library management system project in Python, Let us start creating the project by following step by step approach and in the end, we shall be compiling all the code snippets together to fully implement the Library management system project in Python. We are building the Library management system project in Python where we shall be implementing the data storage using the SQL Database. The SQL Database will consist of various tables to maintain the data associated with the library. We shall be creating different features for our Library management system project in Python as we walk along the article.

The LMS project will be capturing and storing the data in the database called data_library where this database will consist of three tables that will help to capture, store and retrieve the data when required.

Main Menu for Selecting the Different Features of the Library Management System Project in Python

Below is the User defined function that is used to explore the different features of the Library management system project in Python. We have various features as mentioned below that can be used to perform operations on the tables of the databases.

Library Management System Project in Python: Features

Add Books: To add new books with their respective details in the tables. Add Member: To add a new member with its respective details in the tables. Update Book: To update the previously set details of the book. Update Member: To update the previously set details of the member. Issue Book: To issue the book to the member if it's available and store the details of that book. Return Book: To check the return date of the book and charge the fine if the date has been entered. Search Menu: To search for books available on the system. Report Menu: To generate a report of the books and members and their related details. Special Menu: Special menu for additional requirements capturing.

By specifying the options of the scenario which the user wants to undertake to perform on the Library management system project in Python, the specified UDF will be called and action would be performed.

Code:

Explanation: Above we have the UDF main_menu which let us explore the different features of the Library management system project in Python. Once the UDF is called the user gets the chance to choose from the various features and once the choice is entered that respective UDF is called which we shall be discussing in detail as we proceed with the article.

Add Books

The Add Books feature of the Library management system project in Python will help to add the books in the Library management system project in Python where we can store details related to books like Publisher, Author, Number of books, Title, and Price.

Code:

Explanation: As seen above, we created a user-defined function -addition_book in Python which will help us to capture the details associated with the new book addition to the database - library_book. We used the input function to ask the user for the details related to the new book. We also add sql_insert to add the details we captured. Once the book details are captured, by using the print statement we will receive a confirmation message as well.

Add Member

The Add Member feature of the Library management system project in Python will help to add the member details in the Library management system project in Python where we can store details related to members like Class Name, Address of the Member, Member Name, Email Address, and Mobile Number.

Code:

Explanation: As seen above, we created a user-defined function -addition_member in Python which will help us to capture the details associated with the new member added to the database - library_member. We used the input function to ask the user for the details related to the new member. We also add sql_insert to add the details we captured. Also once the member details are captured, by using the print statement we will receive a confirmation message.

Update Book

The Update Book feature of the Library management system project in Python will help to update the previously entered book details in the Library management system project in Python when someone else has borrowed or bought the books which are assigned to another person previously. We can update the details such as Publisher, Author, Number of books, Title, and Price.

Code:

Explanation: As seen above, we created a user-defined function -update_book in Python which will help us to update the details associated with the book. We used the input function to ask the user the details related to the book detail that needs to be updated after which we confirm the book_id and value that is new and needs to be updated. We also add sql_insert to add the details we captured. Once the update details are captured, by using the print statement we will receive a confirmation message as well.

Update Member

The Update Member feature of the Library management system project in Python will help to add the member details in the Library management system project in Python when someone else has borrowed or bought the books which are assigned to another person previously. We can update the details like Class Name, Address of the Member, Member Name, Email Address, and Mobile Number.

Code:

Explanation: As seen above, we created a user-defined function -update_member in Python which will help us to update the details associated with the member. We used the input function to ask the user the details related to the member detail that needs to be updated after which we confirm the member_id and value that is new and needs to be updated. We also add sql_insert to add the details we captured. Also once the update details are captured, by using the print statement we will receive a confirmation message.

Issue Book

The Issue Book feature of the Library management system project in Python will help to issue the books to whom in Library management system project in Python where we can record details related to books like Book ID, if any Fine is pending on any student or a member, Issue Date, Return Date and Member ID.

Code:

Explanation: As seen above, we created a user-defined function -issue_thebook in Python which will help us to update the details associated with the member. We used the input function to ask the user the details related to the book detail that is required for issuing the book. to be updated after which we confirm the member_id and value that is new and needs to be updated. We also add sql_insert to add the details we captured. Also once the update details are captured, by using the print statement we will receive a confirmation message.

Return Book

The Return Book feature of the Library management system project in Python will help to add the return details of the books in the Library management system project in Python where we can store details related to books like when the transactions on books happened once returned by the member.

Code:

Explanation: Here we have created the UDF return_thebook that returns the details of the books after checking to whom it was issued and if that member has extended its day of return or not. If the day of return has been increased then a global fine will be put that is declared at the start of the code snippet. Also we have added three more UDF at the last of the code snippet named status_book(book_id), issuestatus_book(book_id,member_id), and status_member_issue(member_id) that fetch values after running the SQL statements on the tables library_trans and library_book.

Search Menu

The Search Menu feature of the Library management system project in Python will help to search the available books in the Library management system project in Python before issuing it to any member or student. This will reduce manual search time and also come in handy to know the security of the books kept in the library.

Code:

Explanation: As seen above, we are using the user-defined function search_menu() to create a function that contains a while loop that will fetch the book or its related details once we enter the field that we want to search in the whole LMS system. We used the if statements from Python to search between different fields and in return when we call the function serach_menu() it shall return us the details that we specified. We also added the UDF for book_search to check if the book with that specific field and its respective title is present or not.

Report Menu

The Report Menu feature of the Library management system project in Python will help to return the report of the books in the Library management system project in Python with details like Books, Publisher, and Member search.

Here, we have created a small user-defined defined function to generate the report for those scenarios as listed below:

• To generate a report of all the books: booklist_report()

• To generate a report of all the members: memberlist_report()

• To generate a report of all the issued books: issuedbooks_report()

• To generate a report of all the available books: availablebooks_report()

• To generate a report of all the weed-out books: weedoutbooks_report()

• To generate a report of all the lost books: lostbooks_report()

• To generate a report of all the stolen books:

• stolenbooks_report()

• To generate a report of all the fines collected for books: finecollection_report()

Code:

Explanation: As can be seen above, we have created the UDF report_menu() report menu for the choice that gets specified by the user from the REPORT menu. Then as we returned the UDF function based on the scenario we discussed above, we again made use of the UDF in Python to create functions for various scenarios and fetch the list of books and member details as per the scenario by also making use of the SQL select statement in the UDF itself.

Special Menu

The Special Menu feature of the Library management system project in Python will help to add a special menu to our Library management system project in Python. This can act if any special requirement comes into place then it can be incorporated here.

Code:

Explanation: Here we have created a user-defined function - special_menu in Python which lets you access the specific options present. With the help of the input function in Python, we allow the user to select from any one of the options. Also, as we are returning the UDF - change_book_status we have also added the function description at the end of the code snippet. There also we used the sql_update statements to update the values fetched from the special_menu function to be added to the database with the help of the update SQL statements that we combined in the UDF change_book_status.

It's Execution Time

To execute our Library management system project in Python and let our project work, we need to create a database consisting of the three tables- library_book, libraray_member, and library_transaction along with adding a few rows of details to begin executing our project.

Code:

What’s Next

Great Job!!!

Now that we have built our very own we encourage you t have some fun with the source code as well. It would be great if you make some changes in the source code and practice the project from your end as well.

Also, as a challenge, we would like if you to implement the project by incorporating Tkinter which is a standard Graphical user interface library to make it interactive.
