连接四板的问题

Question

我试图让用户在他们的 connect 4 游戏中输入他们想要的行数和列数，所以我试图使用他们的输入来创建棋盘。 我正在尝试创建一个嵌套列表，以便我的其他代码可以工作。 在过去的 2 个小时里，我一直在尝试搜索 web 并绞尽脑汁寻找答案。 这是代码：

    If there is no winner, the function will return the empty string "".
    If the user has won, it will return 'X', and if the computer has
    won it will return 'O'."""

我希望它变成这样的格式；

    # cf_board = [[" ", " ", " ", " ", " ", " ", " "], [" ", " ", " ", " ", " ", " ", " "],
    #             [" ", " ", " ", " ", " ", " ", " "], [" ", " ", " ", " ", " ", " ", " "],
    #             [" ", " ", " ", " ", " ", " ", " "], [" ", " ", " ", " ", " ", " ", " "],
    #             [" ", " ", " ", " ", " ", " ", " "]]

其中行和列取决于用户。 我已经尝试过实现这一目标，但我只得到了这个不被行数和列数分隔的巨大列表。

TL;博士

请帮助我在 main() 修复我的代码，我正在尝试用用户的输入构建一个板

Answer 1

请尝试仅使用最小的可重现示例提出问题。 如果您只是想解决从用户输入构建板的问题，那么只需发布与此相关的必要代码。 要生成开放空间列表的列表，您可以执行以下操作。

row = int(input("How many rows do you want your game to have? "))
col = int(input("How many columns do you want your game to have? "))
cf_board = []
rowLst = []

for i in range(row):
    for j in range(col):
        rowLst.append(" ")
    cf_board.append(rowLst.copy())
    rowLst.clear()

print(board)

for j in range(col) 将一个开放空间附加到一个新列表中。 完成后，该列表将附加到主板列表，然后将 go 清除到下一行。

Answer 2

获得该板非常简单。 不需要 eval 或类似的东西。

只需执行cf_board = [[" "]*col]*row即可根据需要在其中放置尽可能多的空格条目和列表。
