Can any one solve this CS1Robots Module problem?

[kalibardapi212]

the code below is supposed to solve the the rain2.wld world from the cs1robots module. But right now the robot is not finishing its path. Instead it is just going straight. Can anyone do it?

from cs1robots import *

load_world("rain2")
h = Robot(avenue=9, street=3, orientation='S', beepers=10)
h.set_trace("blue")
h.set_pause(0.3)


while not h.on_beeper():
if h.right_is_clear():
h.drop_beeper()
h.move()
if h.front_is_clear():
h.move()
elif h.left_is_clear():
h.turn_left()

This could use improvement, but it should keep the bot inside the room.

while whatever
  (this is the only move that advances the journey)
  move
  (the other moves are reversed)
  if not front is clear
    turn left
  else
    if right is clear
      (should I turn right?)
      move
      if right is clear
        (yes, I should have)
        (I'm off the wall)
        turn left
        turn left
        move
        turn left
      else
        (no, it was a gap, not a corner)
        (reverse the move)
        turn left
        turn left
        move
        turn left
        turn left
