특정 값의 조합에 도달 할 때까지 프로그램을 반복 시키려면 어떻게합니까?

Question

사용자가 (x, y) 격자에서 '보물'을 찾아야하고 올바른 (x, y) 값에 도달 할 때까지 프로그램이 반복되도록이 프로그램을 설계하고 싶습니다. 루프 설계 방법을 찾는 데 도움이 필요합니다.

question = (input("Where do you want to go?: ")); 
y = 0 
x = 0 
if question in ["up"]: 
    y = y + 1 
    print("You've moved up one unit!") 
    print("Your position is now ", x, y) 

if question in ["down"]: 
    y = y - 1 
    print("You've moved down one unit!") 
    print("Your position is now ", x, y) 

if question in ["right"]: 
    x = x + 1 
    print("You've moved right one unit!") 
    print("Your position is now ", x, y) 

if question in ["left"]: 
    y = y + 1 
    print("You've moved left one unit!") 
    print("Your position is now ", x, y)  

else: 
    print("You can't go there.")

시작 힌트 :

treasure_spot = (<somex>, <somey>) 
x = y = 0 
while (x, y) != treasure_spot: 
    <move> 

훨씬 확대 대답 (파이썬 3) 의견에 응답했다. 이것으로부터 몇 가지 배울 점이 있습니다. 이해하는데 어려움이 있다면, CPython 튜토리얼을 읽으십시오.

from random import randint 

maxy = 2 
X = randint(0, maxy)

    } 
print("Your start in the middle of an {0} by {0} field.".format(maxy+1)) 
print("Move around to find the treasure. Here are the moves.") 
print("move meaning") 
for move in ('u', 'ur', 'r', 'dr', 'd', 'dl', 'l', 'ul'): 
    print("{:4s} {}".format(move, directions[move][0])) 

while x != X or y != Y: 
    move = input("You are as {:d}, {:d}. Your move? ".format(x, y)) 
    if move == 'q': 
     break 
    try: 
     dx, dy = directions[move][1] 
    except KeyError: 
     print("Not a legal move.") 
     continue 
    newx, newy = x+dx, y+dy 
    if not (0 <= newx <= maxy and 0 <= newy <= maxy): 
     print("You ran into a fence!") 
     continue 
    x, y = newx, newy 

if move != 'q': 
    print("You found the treasure at {:d},{:d}.".format(X, Y)) 
else: 
    print("Bye, treasure is at {:d},{:d}.".format(X, Y))
