Question

我现在面临着一个问题......我正在尝试制作一个淘气球并且穿越游戏，我正在努力决定用户是否已经猜到了网格之外...这是我的代码到目前为止，结果是代码崩溃，请你帮忙吗？

以下代码是我目前正在运行以获得此结果的代码。

如果数据输入正常，请尝试合并while语句和break 即

while True:
    Down_position = (int(input("How many places would you like to move down")))
    step = Down_position
    if (step + x <= grid_size) and (step + x >= 0):
        x += step
        break
    else:
        print ("Sorry, that isn't on the grid")
        print_board(board)

以下是一些工作代码（仅使用Down）作为示例。

def print_grid():
    print (0,top)
    print ("-----------------------------------")
    for i in range(len(grid)):
        print (i,grid[i])
    print ("-----------------------------------")
x = 0
y = 0
top =[0,1,2,3,4,5,6,7,8,9]
grid=[]
for i in range(10):
    grid.append([0]*10)

grid_size = len(grid)-1
while True:
    while True:
        Down_position = (int(input("How many places would you like to move down ")))
        step = Down_position
        if (step + x <= grid_size) and (step + x >= 0):
            grid[x][y] = 0
            x += step
            grid[x][y] = 1
            print_grid()
            break
        else:
            print("******************************")
            print ("Sorry, that isn't on the grid")
            print("******************************")
            print_grid()

检查变量状态
