Extend the Book class created in the previous question by adding a setter method called “setISBN” that allows code outside the Book class to update or reset the ISBN for the Book object. Before resetting the ISBN first validate it by ensuring the parameter provided is exactly 13 characters long and begins with “ISBN”. If it does, update the Book object’s ISBN value using the same attribute name as the previous question. Return the Boolean False if the provided ISBN does not pass the validation, otherwise reset the ISBN using the parameter and return True. Do not copy or define the entire Book class in this answer. You only have to provide the method.

Create a class called Book that is part of a book store inventory tracking system. Besides title and author, the class has an attribute ISBN (International Standard Book Number) to identify the book and an inventory number, invNo, that tracks each copy of the book the store has in stock. The invNo is generated using a sequence number starting at 1 and incremented each time a new object is created. Show the class’s constructor method that accepts the apropriate attributes as parameters and defines them with the highest protection Python allows. Also show the code for an “equals” method to accept some object as a parameter and return a Boolean value indicating whether the object parameter equals the ‘self’ (internal) object. To get full credit the method must ensure the method does not generate an Exception because the input paramter object does not have one of the attributes used in the method. If the ISBN and invNo are the same the objects are deemed to be equal. Return True if equal, otherwise return False.

Discuss some of the contemporary challenges between Christians and Muslims. Make sure to refer to several examples from the class discussions and readings (answers with details that were not part of our class discussions or readings will receive fewer points). Make sure to spend some time discussing Western political policies that are offensive to Muslims living in the Middle East.
