python - 如何实现列表

Question

我正在尝试创建一个井字棋游戏；但我遇到了一点麻烦。我创建了一个包含数字的列表，因此当选择该数字时，它会更改为 x 或 o。然而，当我的主板打印时，里面有数字 0,1,2,3,4,5,6,7,8，我不希望它们是这样的。我的问题是如何更改空列表中的字符？我会使用索引还是有其他方法来做到这一点

board = [0,1,2,
         3,4,5,
         6,7,8]

def gameBoard():
    print("    " "a" "   " "b" "   " "c")
    print("  ""-------------")
    print(("1"),("|"),board[0],"|",board[1], "|" ,board[2], "|")
    print("  ""-------------")
    print(("2"),("|"),board[3],"|",board[4], "|" ,board[5], "|")
    print("  ""-------------")   
    print(("3"),("|"),board[6],"|",board[7], "|" ,board[8], "|")
    print("  ""-------------")    


while True:
    user_input = input("Enter your move: ")
    if user_input == "a1":
        user_input = "0"
    elif user_input == "a2":
        user_input = "3" 
    elif user_input == "a3":
        user_input="6"
    elif user_input == "b1":
        user_input = "1"
    elif user_input == "b2":
        user_input = "4"
    elif user_input== "b3":
        user_input = "7"
    elif user_input == "c1":
        user_input = "2"
    elif user_input == "c2":
        user_input = "5"
    elif user_input == "c3":
        user_input = "8"
    else:
        print("invalid coordinates")
    user_input= int(user_input)

我猜你想要的是一个带有字符串而不是数字的板，最初填充有单个空格的字符串。您可以为此板使用单个列表或二维数组

单个列表实现

board = [" "," "," "," "," "," "," "," "," "]

控制台示例:

>>> board = [" "," "," "," "," "," "," "," "," "]
>>> board[2] = "X"
>>> board
[' ', ' ', 'X', ' ', ' ', ' ', ' ', ' ', ' ']
>>> board[0]
' '
>>> board[2]
'X'
>>> 

二维数组实现

board = [[" "," "," "],[" "," "," "],[" "," "," "]]

控制台示例:

>>> board = [[" "," "," "],[" "," "," "],[" "," "," "]]
>>> board[1][2] = "O"
>>> board
[[' ', ' ', ' '], [' ', ' ', 'O'], [' ', ' ', ' ']]
>>> board[0][1]
' '
>>> board[1][2]
'O'

打印二维列表的示例:

>>> board = [["X"," ","X"],[" ","X"," "],["X"," ","X"]]
>>> for row in board:
    string = ""
    for element in row:
        string = string + element
    print(string)


X X
 X 
X X
