Python3缩进错误

尽管看到了很多关于python缩进错误的帖子，并尝试了很多解决方案，但我还是发现了这个错误：

            system.exit()

我知道这是一段相当长的代码，但我将指出错误所在的特定区域。您知道，我收到以下错误消息：

    Traceback (most recent call last):
  File "python", line 106
    if (win(the_board,pla) == True):
                                   ^
IndentationError: unindent does not match any outer indentation level

更具体地说，这部分代码：

while True:
                number = player_move(the_board)
                if (valid_move(the_board,number) == True) and not(board_full == False):
                    make_move(the_board,number,pla)
                    break
                else:
                    print("Invalid Move, try again!")
                    continue
             if (win(the_board,pla) == True):
                print ("Yay, you won!!!")
                printboard(the_board)
                count = 1
                break

有什么帮助吗？我无论如何都不能让代码正常工作

尝试将前七行代码取消识别一个级别（该

while

循环中的代码）。这将使缩进正常工作。另外，在导致错误的

if

语句之前似乎还有一个额外的空格。也请删除此空间。这将使代码的这一部分如下所示：

while True:
        number = player_move(the_board)
        if (valid_move(the_board,number) == True) and not(board_full == False):
            make_move(the_board,number,pla)
            break
        else:
            print("Invalid Move, try again!")
            continue
        if (win(the_board,pla) == True):
            print ("Yay, you won!!!")
            printboard(the_board)
            count = 1
            break

---

您需要在

下缩进块，同时（True）：

保持一致。例如：

while True:
    number = player_move(the_board)
    if (valid_move(the_board,number) == True) and not(board_full == False):
        make_move(the_board,number,pla)
        break
    else:
        print("Invalid Move, try again!")
            continue

    if (win(the_board,pla) == True):
        print ("Yay, you won!!!")
        printboard(the_board)
        count = 1
        break
    else:
        turn = "comp"
        printboard(the_board)
        continue

---

问题是，if语句是代码其余部分的缩进。您希望对齐所有代码，错误应该消失

while True:
     number = player_move(the_board)
     if (valid_move(the_board,number) == True) and not(board_full == False):
         make_move(the_board,number,pla)
         break
     else:
        print("Invalid Move, try again!")
        continue
     if (win(the_board,pla) == True):
        print ("Yay, you won!!!")
        printboard(the_board)
        count = 1
        break

---

看看代码。这显然是错的！看到它怎么没有对齐了吗？

为True时：

靠近末尾的行是错误的。它与它上面的

continue

处于同一级别。但是

continue

跳回循环的开头，因此它之后不会执行任何操作。
