Complete exercise 9.7 in ThinkPython. As explained in the text, you will need to download this list of words and save it to a file where your Python program can read it. You will write a Python program to find a word that contains three consecutive double letters. Write an original program. Use the book, not the internet, to solve this problem. For example, there is a trivial solution using regular expressions but those aren't covered in the book so don't use them.
