Question

我在代码大战中输入代码时遇到此错误。 “回溯：在模块中在damaged_or_sunk中 IndexError：列表索引超出范围“。但是，当我在spyder3中尝试我的代码时，它工作正常。但是没有关于函数damaged_or_sunk中此错误的位置的指示器。

def damaged_or_sunk (board, attacks):        
    a = sum(x.count(1) for x in board)
    b = sum(x.count(2) for x in board)
    c = sum(x.count(3) for x in board) 
    a1 = 0
    b1 = 0
    c1 = 0               
    points = 0
    sunk = 0
    damaged = 0
    not_touched = 0


    for each in attacks:
        rand_row = each[0]
        rand_col = each[1]

        if board[rand_row][rand_col] == 1:
            a1 += 1
        elif board[rand_row][rand_col] == 2:
            b1 += 1
        elif board[rand_row][rand_col] == 3:
            c1 += 1
        else:
            pass

    if a1 == a:
        points += 1
        sunk += 1
    elif a1 == 0:
        points -= 1
        not_touched += 1
    else:
        points += 0.5
        damaged += 1

    if b1 == b:
        points += 1
        sunk += 1
    elif b1 == 0:
        points -= 1
        not_touched += 1
    else:
        points += 0.5
        damaged += 1

    if c1 == c:
        points += 1
        sunk += 1
    elif c1 == 0:
        points -= 1
        not_touched += 1
    else:
        points += 0.5
        damaged += 1    

    return '{\'sunk\': %s, \'damaged\': %s, \'not_touched\': %s, \'points\': %s}' %(sunk, damaged, not_touched, points)

attacks中的情侣包含(x, y)坐标，这些坐标必须是列表索引。

我假设它们是随机生成的，请确保：

0 <= x < len(board[0])
0 <= y < len(board)
all( len(board[0]) == len(board[row]) for row in board)

字符串索引必须是整数战舰代码战卡塔
