20 import random 21 22 23 def getBookAsString(fileName): IF IT IT 24 25 26 27 Read all lines in the book and append them to the one big string. A space is added at the end of each line to avoid having the last word on a line be appended to the first word on the next line. 1 return 'Under Construction' I 28 29 30 31 32 33 34 # Test code: testText = getBookAsString('weHold.txt') # We need the blank space at the end of this long string assert(testText == "We hold these truths to be self-evident: that all men are created equal; "that they ") 35 36 + 37 38 39 40 41 def getListofFollowers (theBook, nGram): IF 42 43 Using the algorithm on the last slide of RandomWriter.pdf, create the complete list of all followers of nGram that are in the book. IF IT I 45 46 return [] 47 48 49 50 51 52 53 # Test code testBook = getBookAsString('weHold.txt') testFollowers = getListofFollowers(testBook, 'th') assert(testFollowers ['e', 's', 'a', 'a', 'e']) testIndex = random.randint(0, len(testFollowers) - 1) assert(testIndex
