I think with this lab, it was harder to detect when the code I wrote
was not what I wanted. With the drawings in unit 1, you can tell what
is off because you see what the code creates, and you get an error
message. With this, you can't easily see what is off because you are
just seeing a very long list of words. For this lab, I feel like I had
to "check my work" by printing some of the intermediate steps and
making sure they made sense.
