Python 3 - 数字标记网格和添加边框？

Question

我正在尝试添加数字标签，以及一行和一列来为我的程序组织我的游戏板。我注意到如果我使 emptyGrid = ["OOOO", "OOOO", "OOOO", "OOOO"] 会起作用，但是 sizeof_grid 应该代表用户输入的任何值，所以我不能真正使 emptygrid 相等到设定的网格大小。也就是说，当 emptygrid = [] 时，我无法让程序显示网格标签。当我用我当前的程序执行此操作时，它什么也不打印。

sizeof_grid = 4
emptyGrid = []

def initialize_board():
    start_board=[["O" for i in range(sizeof_grid)] for i in 
range(sizeof_grid)]
    return start_board

def players_board(grid): 
    for i in range(len(grid)): 
        print(str(i) + "|" + grid[i])
print(players_board(emptyGrid))

我希望代码输出如下内容:

|01234

0|呜呜呜

1|呜呜呜

2|呜呜呜

3|呜呜呜

4|呜呜呜

(每行之间没有空格)

您的代码中有一些错误。您不调用 initialize_board 函数。此外，players_board 函数中也存在一些错误。

修改后的代码(有变化的行注释并解释变化):

sizeof_grid = 4
emptyGrid = []

def initialize_board():
    start_board = [["O" for i in range(sizeof_grid)] for i in 
range(sizeof_grid)]
    return start_board

def players_board(grid):
    print(" |" + "".join([str(x) for x in range(len(grid[0]))]))  # print the column numbers
    for i in range(len(grid)): 
        print(str(i) + "|" + "".join(grid[i]))  # convert the list to "" joined chars

emptyGrid = initialize_board()  # call this to initialize the board
players_board(emptyGrid)

HTH.
