As you should have noticed the program doesn’t work. What happens is that Reeborg gets in an infinite loop when there is no wall around him. We need to have him move() after turning right, as indicated below:
put() move() while not object_here(): if right_is_clear(): turn_right() move() elif front_is_clear(): move() else: turn_left()
Now, consider Around 3; will our program work?
As you probably guessed, unfortunately the answer is no. Try to figure out why before reading any further.
