I would name it books in both cases.Īlso be consistent with the names of functions: In class Library, the list of books is called books, but in class ReadlingList you named it list. That is a bit surprising.Īlso be consistent with naming things. You take an optional list of books in the constructor of class Library, but there is no such thing in class ReadingList. Note that to prevent the issue of mutable default arguments as mentioned by ojdo, you should make a copy of the initial list. Why not use as the default value? class Library: You have a default value of None for the parameter books, but then immediately proceed to convert that None to an empty list. Simplify the constructor of class Library My_lib.new_book(Novel("Aryan Parekh","Stack")) My_lib.new_book(Novel("J.K Rowling","Harry Potter")) # Comic book stuff which isn't common in all books # Novel stuff which isn't common in all books Return ĭef _init_(self, title, pages, publicationDate):
"""Returns books that have more than specified number of pages""" I don't know if there's a way to deal with this, or if I'm thinking about this the wrong way. Also there is an issue whereby if you remove a book from the library, it will still show up in any reading lists I created. Speaking of structure, I would just like to know if mine is any good. But hopefully from the below you get a good idea of the structure. Note that I've removed quite a lot from this, just so it's not 5 pages long! I would normally have several different types of books, attributes such as Author etc. For example, a library method which will return all books over a specified length. Program allows one to add books (comics or novels - with comics inheriting from novels) to one's own library, and create a custom reading lists. However I thought I'd put together a personal online book library to practice inheritance, methods, docstrings etc. The individual who dropped off The Perennial Philosophy also managed to dodge 27 years of late fees because the library opted to eliminate fines in April of this year.Very new to OOP with Python - and feel like I still don't totally get OOP. "Our members are more important to us than.the overdues and losts that might happen occasionally." "We know sometimes overdues happen because of the monsters under the bed or because everything can fall to the bottom of a knapsack," Weaver told CBC. Library spokesperson Melanie Cummings told CBC that the DVD collection has the most missing items.Īlthough it may take some time for some library materials to find their way back to the shelves, the library will welcome them back with open arms.
Items marked lost before December 2018 are deleted from the system. "We hope the book has had a few great few decades away from the Hamilton Public Library."ĬBC reported more than 7,000 library items are considered lost, but that number represents less than 1 percent of the collection. "We do know that our books go on a lot of adventures in our city, our country, around the world," she said. Lisa Radha Weaver, the library's director of collections and program development, told CBC she wasn't sure where the book has been when it was off of the shelves. "HPL originally had this book on its shelves in 1980, and was last checked out on December 13, 1993. "Look what #TeamHPL found in one of our drop boxes recently!" a tweet from the library read. But one reader returned their copy of The Perennial Philosophy to Canada's Hamilton Public Library 27 years after it was borrowed. It's easy to hang on to a library book for a few extra days, maybe even a week past its due date.
