I have been learning programming in Python recently and I got a task to program a library in OOP. You can add books to library,search for a specific book according to the ISBN ,name of the author or search books which cost less than price. Everything seems to be okay, but I am new to OOP so I would like to hear some advices whether it is programmed a “good way” or not . Thanks
class Library(object): books =  written_by_author =  books_under_price =  def __init__(self, name, author, isbn, price): self.name = name self.author = author self.isbn = isbn self.price = price def addBook(self): Library.books.append((self.name,self.author,self.isbn,self.price)) def searchBookISBN(self,isbn): for book in Library.books: if book==isbn: return book def searchBookAuthor(self,author): for book in Library.books: if book==author: Library.written_by_author.append(book) return Library.written_by_author def searchUnderPrice(self,price): for book in Library.books: if book<price: Library.books_under_price.append(book) return Library.books_under_price book = Library('Geometry', 'Jeff Potter', '0596805888', 22) book.addBook() book = Library('Math', 'George Harr', '0594805888', 15) book.addBook() book = Library('English', 'James Odd', '0596225888', 10) book.addBook() book = Library('Physics','Jeff Potter','0597884512',18) print (book.searchBookISBN('0594805888')) print (book.searchBookAuthor('George Harr')) print (book.searchUnderPrice(20))
