This is a simple Library Management System built using Object-Oriented Programming (OOP) in Python.
The system allows users to:
View all available books.
Lend (borrow) books by user name.
Add new books to the library.
Return borrowed books.
Remove books from the collection.
View the list of customers.
Add new customers.
The system keeps track of which users have borrowed which books, ensuring no book is borrowed twice without being returned first.
