Classes Practice

You've been tasked with writing the code for the wizard library. Complete the Library and Book classes listed below.

1. Complete the Book Class:
   1. Complete the __init__(self, title: str, author: str) -> None method
      1. Set .title and .author to the values of the parameters
2. Complete the Library Class:

   1. Complete the __init__(self, name: str) -> None method

      1. Initialize a .name member variable to the value of the name parameter
      2. Create a .books member initialized to an empty list

   2. Complete the add_book(self, book: Book) -> None method:

      1. Add book, the given Book instance, to the library's books instance variable by appending it to the end of the list

   3. Complete the remove_book(self, book: Book) -> None method:

      1. Create a new, empty list to hold the books you want to keep
      2. Loop through every book in the library's books list
         1. If the book's title and author both match the one you want to remove, don't add it to the list. Otherwise, add it.
         2. After checking all the books, replace the library's books list with the new list

      When removing items, it is safer to create a new list of what you want to keep. Deleting items directly during a loop shifts the indices of the remaining items, causing the loop to skip data.

   4. Complete the search_books(self, search_string: str) -> list[Book] method:

      1. For every book in the library check if the search_string is contained in the title or author field (case-insensitive)
      2. Return a list of all books that match the search string, ordered in the same order as they were added to the library

• You can use the .lower() method to convert a string to lowercase.
• Avoid modifying a list while looping over it because it can skip items or cause errors; instead, create a new list with the items you want to keep or loop over a copy.
