Whenever I run this file I get a IndexError: string index out of range, not sure where I'm going wrong here

Question

首先，post 很抱歉，如果这不是格式化所有内容的正确方法，但我正在尝试为两个玩家制作一个 connect 4 游戏，但我不明白为什么我收到此错误。

#Creates the board
def Boardmaker(field):
    for row in range(12): #0,1,2,3,4,5,6,7,8,9,10,11
        NewRow = int(row/2)
        if row%2 == 0:
            for column in range(13):
                NewColumn = int(column/2)
                if column%2 == 0:
                    if column != 12:
                        print(field[NewColumn][NewRow],end="")
                    else:
                        print(field[NewColumn][NewRow])
                else:
                    print("|",end="")
        else:
            print("-------------")

#Play space
player = 1       #0    1    2    3    4    5    6
Currentfield = [[" ", " ", " ", " ", " ", " ", " "], 
                [" ", " ", " ", " ", " ", " ", " "], 
                [" ", " ", " ", " ", " ", " ", " "], 
                [" ", " ", " ", " ", " ", " ", " "], 
                [" ", " ", " ", " ", " ", " ", " "], 
                [" ", " ", " ", " ", " ", " ", " "], 
                [" ", " ", " ", " ", " ", " ", " "]]

#Player Controller and turn allocator
Boardmaker(Currentfield)
while(True):
    MoveColumn = int(input("Please enter a column"))
    if player == 1:
        #if Currentfield[MoveColumn] == " ":
            Currentfield[MoveColumn] = "X"
            player = 2
    else:
        #if Currentfield[MoveColumn] == " ":
            Currentfield[MoveColumn] = "O"
            player = 1
    Boardmaker(Currentfield)

Answer 1

在代码中

if player == 1:
    #if Currentfield[MoveColumn] == " ":
        Currentfield[MoveColumn] = "X"
        player = 2

您正在用字符串 "X" 替换 Currentfield 的列表之一，因为您没有指定行索引。然后，在打印游戏板时迭代这个字符串，因为这是一个长度为 1 的字符串，所以你得到索引错误。

Answer 2

在 connect 4 游戏中，您必须设置棋盘的 column 和 row，您的代码将是：

player = 1
Currentfield = [[" ", " ", " ", " ", " ", " ", " "], [" ", " ", " ", " ", " ", " ", " "], [" ", " ", " ", " ", " ", " ", " "], [" ", " ", " ", " ", " ", " ", " "], [" ", " ", " ", " ", " ", " ", " "], [" ", " ", " ", " ", " ", " ", " "], [" ", " ", " ", " ", " ", " ", " "]]
while(True): 
    MoveColumn = int(input("Please enter a column:"))    
    MoveRow = int(input("Please enter a row:"))
    if player == 1:
        #if Currentfield[MoveColumn] == " ":
        Currentfield[MoveColumn][MoveRow] = "X"
        player = 2
    else:
        #if Currentfield[MoveColumn] == " ":
        Currentfield[MoveColumn][MoveRow] = "O"
        player = 1            
    Boardmaker(Currentfield)

此外，我注意到您没有正确使用列表的索引，首先是 row，然后是 column，上面的代码应该可以在您的程序中使用，但是，如果您想要更改它，只需将 field[NewColumn][NewRow] 更改为 field[NewRow][NewColumn] 并将 Currentfield[MoveColumn][MoveRow] 更改为 Currentfield[MoveRow][MoveColumn]
