Your class should have a creator that takes the 4 values and assigns them to the attributes isbn, title, author, and type. Type may be: "F" for fiction, "N" for non-fiction, or "B" for Biography. Your class should also have a __str__ method that will return a string of the isbn, the title, the word by, the author, and type in parenthesis. Seperate all of these values with a space. In a main def (outside the class) create an instance of the class Book with an ISBN number of 1234567890123, a title of "The Great American Novel", the author "Wanna B. Author" and the type "F".
