Question

出现此错误。我不知道它是什么。我是初学程序员。

ConnectFourBoard.py“，第58行，在show_board_dynamic中 print（self .__ board [i] [j]，end =“”），IndexError：列表索引超出范围

我的代码：

class ConnectFourBoard:
    def __init__(self, cols = 7, rows = 6, requiredToWin = 4):
        global __board
        self.__space = ''
        self.__board = []
        self.cols = cols
        self.rows = rows
        self.Win = requiredToWin
        self.__board = [[''] * rows for i in range(cols)]

        for i in range(cols):
            row = ['']*cols
            self.__board.append(row)

    def MakeMove(self, row, col, element):
        global __board
        self.__board[row][col] = element

    def CheckForWin(self):
        return winner

    def CheckHz():
        for x in range (6):
            for y in range (7):
                row += board[x][y]
                print("%s" %row)
                row = ""
                if "XXXX" in row:
                    print("Winner is X")
                    break;

    def CheckVt():
        for y in range(7):
            for x in range(6):
                column += board[y][x]
                print("%s" %column)
                column = ""
                if "XXXX" in column:
                    print ("Winner is X")
                    break;




    def FullBoard(self):
        return True

    def FreeSpace(self, row, col):
        return True

    def show_board_dynamic(self):
        print()
        print("-------")
        for i in range(len(self.__board)):
            for j in range(len(self.__board)):
                print("|", end = "")
                print(self.__board[i][j], end = ""),
            print("|")
            print("-------")
        print()

Answer 1

对于行和列，您有不同的数字，但对于这两个数字，您只需要len(self.__board)进行迭代。

变化：

    for i in range(len(self.__board)):
        for j in range(len(self.__board)):
            print("|", end = "")
            print(self.__board[i][j], end = ""),
        print("|")
        print("-------")

为：

    for col in self.__board:
        for val in col:
            print("|", end = "")
            print(val, end = ""),
        print("|")
        print("-------")

Answer 2

你应该

将棋盘更改为正方形，以便行= cols。
分别删除行和列的默认参数6和7。
6行和7列的硬编码

有很多方法可以解决在整个程序中没有同步行和列的错误。

        for i in range(len(self.__board)):
            for j in range(len(self.__board[0])):

此行应固定于此。
