Draw a capital I with a black pen that is 2 pixels thick. The letter is one straight line, 80 pixels high, centered in a 40-pixel-wide space.

The turtle starts at the center of the canvas, facing east. This is the bottom-left corner of the letter’s space.

1. Lift the pen and move forward 20 pixels to the middle of the space.
2. Put the pen down. Turn left and move forward 80 pixels.
