text: # 8.4 Open the file romeo.txt and read it line by line. For each line, split the
  # line into a list of words using the split() method. The program should build a
  # list of words. For each word on each line check to see if the word is already
  # in the list and if not append it to the list. When the program completes, sort
  # and print the resulting words in alphabetical order.
  # You can download the sample data at http://www.py4e.com/code3/romeo.txt
