python - 如何在 Python 中填充二维数组？

Question

这是我的代码:

empty = ' '
board = [[empty, empty, empty], [empty, empty, empty], [empty, empty, empty]]

def print_board():
    for idx, val in enumerate(board):
        print(val)

def board_update(x,y,player):
    board[x:y] = player;

game_is_running = True
player = 'x'
print_board()



while game_is_running:
    if player == 'x':
        print ('x turn')
        ver = int(input('input vertical of x '))
        hor = int(input('input horizontal of x '))
        board_update(ver, hor, player)
        player = 'o'
    print_board()

    if player == 'o':
        print ('o')
        vertical = int(input('input vertical of o '))
        horizontal = int(input('input horizontal of o '))

每当我运行代码时，它都会像这样放置字母:

[' ', ' ', ' ']

x

[' ', ' ', ' ']

[' ', ' ', ' ']

如何让它看起来像这样:

[' ', ' ', ' ']

[' ', x ,  ' ']

[' ', ' ', ' ']

Answer 1

这里的问题是一致的

board[x:y] = player;

[x:y] 表示法用于分配范围，而您真正需要的可能是

board[x][y] = player

通常您会收到错误，因为将单个值分配给范围会抛出TypeError。在这种情况下，您正在分配 python 将其视为字符列表的字符串。
