Answer 1

import sys
class Library:
      def __init__(self,listofbooks):#this init method is the first method to be invoked when you create an object
            #what attributes does a library in general have? - for now, let's abstract and just say it has availablebooks (we're not going to program the shelves, and walls in!)
            self.availablebooks=listofbooks

      def displayAvailablebooks(self):
                   print("The books we have in our library are as follows:")
                   print("================================")
                   for book in self.availablebooks:
                         print(book)
      def lendBook(self,requestedBook):
            if requestedBook in self.availablebooks:
                  print("The book you requested has now been borrowed")

      def addBook(self,returnedBook):
            self.availablebooks.append(returnedBook)
            print("Thanks for returning your borrowed book")
