Python:连接4播放

Question

嗨，我是 python 新手，我正在创建一个 connect 4 游戏，我正在最后一点，即允许玩游戏的 play 函数。问题似乎是我的 while 循环，它运行一次，询问用户一列并在该列中输入计数器，但是之后它只是继续询问选择哪一列而不更改板:

who = game['who']
    while who != 'computer':
        x = int(input("Which column to select? "))
        game['board'] = board2
        l = getValidMoves(game['board'])
        if x in l:
            game['board'] = makeMove(board2, x, who)
            printBoard(game['board'])            
            board = game['board']
            if hasWon(game['board'], who) == True:                        
                print("{who} has won.")
                sys.exit()

你可以看到当我运行这段代码时我得到:

Which column to select? 1
|1|2|3|4|5|6|7|
---------------
| | | | | | | |
| | | | | | | |
| | | | | | | |
| | | | | | | |
| | | | | | | |
| |X| | | | | |

Which column to select? 2

Which column to select?

我认为问题在于 while 循环在询问要选择哪一列后停止运行。任何帮助将不胜感激。

我的 printBoard 功能是:

print("|1|2|3|4|5|6|7|")
    print("---------------")        
    for j in range(6):
        for i in range(7):
            if board[j][i] == 1:
                board[j][i] = "X"
            elif board[j][i] == 2:
                board[j][i] = "O"
            elif board[j][i] == 0:
                board[j][i] = " "                           
    for j in range(6):
        print("|"+"|".join(str(board[j][i]) for i in range(7))+"|")   
    return None

我的 getValidMoves 是:

l = list()
for i in range(7):
    if board[0][i] == 0:
        l.append(i)   
return l
enter code here

我的 makeMove 是:

if who == 1:
    for i in [5,4,3,2,1,0]:
        if board[i][move] == 0:
            break
    board[i][move] = 1

elif who == 2:
    for i in [5,4,3,2,1,0]:
        if board[i][move] ==  0:
            break
    board[i][move] = 2              
return board

Answer 1

只要 who 不等于“computer”，循环就会继续。但循环内的任何内容都不会改变 who，因此它永远不会等于“computer”，循环也永远不会完成。
