Question

我正在为n x n游戏创建一个零交叉游戏（用户将输入棋盘的大小）。

到目前为止，我已经能够创建一个在用户输入他们想要的板子尺寸后在列表的每个元素中都带有下划线的板子。

但是，我的问题是，当玩家放下一个标记时，他们要通过输入行号和列号来实现，它输入整列的标记。

例如，标记在板上放置的行是以下行：board[int(row)-1][int(column)-1] = symbol。如果用户输入1、1，则应在板的左上角第1行和第1列中放置一个标记。但是，它将在整列中输入标记。我很困惑为什么要这样做。帮助表示赞赏！

（#Checking if someone won下的行与该问题无关。要查看的主行在#Putting the marker on the board和#Creating the board下。）

#todo:
#check if marker already is there

board = []
empty_list = []

board_length = input("How many rows would you like for the board? ")
while board_length.isdigit() == False:
    board_length = input("That is not a number. How many rows would you like for the board? ")

#Creating the Board
for x in range(int(board_length)):
    board.append(empty_list)
    board[x].append('_')

#Printing the board

    print(board[i])

#Setting correct answers for coordinates

    #Making sure the coordinates entered are correct
    row = input("Player " + player_name + ": Please enter the row for your marker: ")
    while row not in correct_answers:
        row = input("Invalid answer. Please enter the row for your marker: ")

Answer 1

更改：

board.append(empty_list)

收件人：

board.append([])

通过一遍又一遍地使用相同的empty_list，您将创建许多对同一列表的引用。以后更改列表时，通过所有引用都可以看到它。
