Question

现在我正在尝试将一个2D数组（列表列表）放入我在Python中的扫雷程序中。但是，当我运行它时，它会给我一个38行错误

   Traceback (most recent call last):

   File "F:\MINESWEEPER2.py", line 112, in <module>

    check_neighbours(reveal,board,bombs)

   File "F:\MINESWEEPER2.py", line 38, in check_neighbours

    board[index] = bombcount #copy the number of neighbouring bombs

   IndexError: list assignment index out of range).

代码：

 import string
 import os
 import random
 def check_neighbours(index, board, bombs):

#get the last digit in the index to check for left or right column positions
if index > 9:
    strindex = str(index)
    second = strindex[1]
else:
    second = 'a'

if index == 0:  #top left corner
    offsets=[1,10,11]
elif index == 9:    #top right corner
    offsets =[-1,9,10]
elif index == 90:   #bottom left corner
    offsets = [-10,-9, 1]
elif index ==99:    #bottom right corner
    offsets=[-11,-10,-1]
elif index > 0 and index < 9: #top row 
    offsets = [-1,1,9,10,11]
elif index >90 and index < 99:  #bottom row
    offsets = [-1,1,-9,-10,-11]
elif second == '9':     #Right side column
    offsets=[-11,-10,-1,9,10]
elif second == '0':     #Left side column
    offsets = [-10,-9,1,10,11]

else:
    offsets=[-11,-10,-9,-1,1,9,10,11]
bombcount = 0;
for i in offsets:   #check for bombs in all neighbour positions
    if index+i in bombs:
        bombcount+=1

board[index] = bombcount #copy the number of neighbouring bombs
if bombcount == 0:
    board[i][j] = ' '
    for i in offsets:   #Recursive function call for all neighbours
        if board[index + i] == '*':
            check_neighbours(index+i, board, bombs)


else:
    return



def print_reveal(board, bombs):
count = 0

rowcount = 0
for i in board:
    if count in bombs:
        i = 'B'
    print("| ", i, end=" ")
    if rowcount == 9:
        print("|")
        rowcount = 0
    else:
        rowcount += 1
    count += 1

board = []
bombs = []
for i in range(10):
 board.append([])
  for j in range(10):
    board[i].append('*')

for i in range(10):
 for j in range(10):
    print("|", board[i][j], end=" ")
print("|")
bombs = []
for i in range(10):


loc = random.randint(0, 99)
while loc in bombs:
    loc = random.randint(0, 99)
#board[loc] = 'B'
bombs.append(loc)


gameon=True
while(gameon):

choice = input("Do you want to pick a spot or flag a bomb? (pick or flag)")
if choice == 'flag':
    bombloc = int(input("Enter your guess for a bomb location: "))
    if bombloc >= 0 and bombloc < 100:
        if board[bombloc] != '*':
            print("already chosen!")
        else:
            board[bombloc] = 'F'



else:

    reveal = int(input("Enter your guess for an open spot: "))
    if reveal >= 0 and reveal < 100:
        if board[i][j] != '*' and board[i][j] != 'F':
            print("already chosen!")
        elif reveal in bombs:
            print("BOOOM!!!")
            gameon = False
        else:
            check_neighbours(reveal,board,bombs)



if '*' not in board:
    print("You WIN!")
    gameon = False

if(gameon):
    print_reveal(board,bombs)
print(bombs)

这是输出：

   | * | * | * | * | * | * | * | * | * | * |
   | * | * | * | * | * | * | * | * | * | * |
   | * | * | * | * | * | * | * | * | * | * |

   | * | * | * | * | * | * | * | * | * | * |
   | * | * | * | * | * | * | * | * | * | * |
   | * | * | * | * | * | * | * | * | * | * |
   Do you want to pick a spot or flag a bomb? (pick or flag)pick

   Enter your guess for an open spot: 30

我不知道如何解决此问题

我真的很感谢这方面的帮助

问题似乎是你永远不会初始化你的电路板。在print_reveal的早期，您执行：board = []（覆盖作为参数传递的board值），但之后永远不会填充board。之后，当您检查玩家选择的位置时，您会从IndexError获得if board[bombloc] != '*':，因为board仍为空列表。

你需要决定print_reveal是否应该创建董事会。如果没有，只需删除board = []行（并确保传入的参数是合适的）。否则，您应该摆脱令人困惑的参数，并使用适当的值（可能是board = ["*"] * 100）设置电路板，而不是使用未初始化的电路。
