Answer: replace searchTheBook() with below given code and modify the main() function with below given code

import sys, os
__location__ = os.path.realpath(os.path.join(os.getcwd(), os.path.dirname(__file__)))

def openTheBook(bookname):
   """ Function that opens a book. The book is returned as as string.
   Parameters: The name of the book, as a string
   Returns: The text of the book, as a string
   Assumptions: The file containing the book is in the same folder
   as this Python program.
   """
   # open the file. Again, use this code. The variable 'bookname' has the name
   # of the file that contains the book
   textFile = open(os.path.join(__location__,bookname), 'r')
   # the book is now open. Read the book into a list, then close the book.
   bookList = [] # empty list

   for line in textFile:
       #print line
       bookList.append(line) # add the line to the bookList list

   textFile.close()

   # return the book's contents as a list to the calling function
   return bookList

def searchTheBook(bookname):
   """ Function that processes the contents of a book.
   Parameters: The name of the book to be processed
   Returns: nothing. All information is displayed on the screen.
