Part of the assignment for Session04

I am leaving tomorrow morning on a trip for work.  I'm checking in all of this week's assignment except for the trigrams portion, which I haven't gotten to yet.  I'm hoping that I will find the time to work on that over the next several days while I am away on travel, but I'm not sure what kind of progress I will be able to make.
You are skipping the last word. Remember if you do range(len(myvariable)) it includes the last word, so to get the end 3 words, you just need to subtract 2 to get the other 2: for i in range(len(allwords) - 2): 
Not sure how much sense that explanation makes, so probably best to play around with a list of a few numbers and see what you get when you loop through printing various groups of the numbers.
