Remember the following?
Can you figure out on your own what the following program does, without copying it in the editor and having Reeborg obey the instructions?:
def a(): turn_left() turn_left() def b(): turn_left() a() def c(): move() move() def d(): c() b() def e(): d() d() d() d() turn_left() e() b()
Not so easy, is it?
Once you think you have figured out what the above code does, copy it in the editor and run it to confirm your understanding.
This should help you to understand why it is important to write programs for humans, by choosing function names that are meaningful.
