# Exercises
This lesson only had five problems, and thank goodness for that, because problem 4 really threw me for a loop. I've included all 5 here, because there are so few problems and because I genuinely found them all to be interesting problems. 
Also I kept getting tripped up with how I interpreted the numbers from the files vs how Python interpreted them. Because they were coming from a file, those numbers were interpreted as strings, not numbers. You'd think that after my first encounter with this, I'd understand that, but I was literally still struggling with that on problem 5 lol.

Anyway, enough talk. Let's go through the exercises.

> At the bottom of this page is a very long file called `mystery.txt` The lines of this file contain either the word UP or DOWN or a pair of numbers. UP and DOWN are instructions for a turtle to lift up or put down its tail. The pairs of numbers are some x,y coordinates. Write a program that reads the file `mystery.txt` and uses the turtle to draw the picture described by the commands and the set of points.
It's long so, I'll just link to the data in `mystery.txt` [here](Exercises/mystery.txt.md).

Drawing the image was relatively straightforward. It was getting the world coordinates that was challenging, even though I literally just did the same thing in the previous problem.
