While loops

What about the for loop:

for item in list_of_items:
  #Do something to each item

for number in range(a,b):
  print(number)

While

while something_is_true
  #Do something repeatedly

while +condintion:

Infinite loop

if you don't know why it is an infinite loop, just print the condition.

def turn_right():
    turn_left()
    turn_left()
    turn_left()
def jump():
    turn_left()
    while front_is_clear() and wall_on_right():
        move() 
    turn_right()
    move()
    turn_right()
    move()
    while front_is_clear() and wall_on_right():
        move() 
    turn_left()
while not at_goal():
    if front_is_clear():
        move()
    elif wall_in_front():
        jump()

成功啦！！！
