Need a reminder? The key ideaShow
len(words) counts all. len(set(words)) counts the different ones.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, compare your working with the solution.
split() gives the list of words: to, be, or, not, to, be. That is 6 words.
set(words) keeps each word once: to, be, or, not. That is 4 different words.
