Consider the following class declaration...

class Book: def $\_\_$init$\_\_($self$,$ title: str $="",$ authors: list$[$str$]=$ None$)$: self.$\_\_$title $=$ title self.$\_\_$authors $=$ authors

Make the necessary changes to the class declaration so that the following code would output each author, one per line..

def main$()$: book$\_1=$ Book$("$Foundation$",["$Isaac Asimov"$])$ for author in book$\_1$: print$($author$)$ if $\_\_$name$\_\_=="\_\_$main$\_\_"$: main$()$
