在Connect Four Printing匹配芯片的匹配功能（python）

Question

我有一个适当运行的Connect Four程序，但我想将match_in_direction（）方法打印到屏幕上...我的代码如下

class ConnectFour(object):

这初始化了董事会：

    def __init__(self):
        self.board = [[None for i in range(7)] for j in range(8)]

这得到了每个游戏点的位置：

    def get_position(self, row, column):
        assert row >= 0 and row < 6 and column >= 0 and column < 7
        return self.board[row][column]

这应该检查所播放的筹码是否匹配：

    def match_in_direction(self, row, column, step_row, step_col):

    assert row >= 0 and row < 6 and column >= 0 and column < 7
    assert step_row != 0 or step_col != 0 # (0,0) gives an infinite loop

    match = 1

    while True:
        nrow = row + step_row
        ncolumn = column + step_col
        if nrow >=0 and nrow <6 and ncolumn >=0 and ncolumn <7:
            if self.board[row][column] == self.board[nrow][ncolumn]:
                match == match+1
                row = nrow
                column = ncolumn
            else:
                return match
        else:
            return match
    print match

这将是基于用户输入的游戏

    def play_turn(self, player, column):
    """ Updates the board so that player plays in the given column.

    player: either 1 or 2
    column: an integer between 0 and 6
    """
    assert player == 1 or player == 2
    assert column >= 0 and column < 7

    for row in xrange(6):
        if self.board[row][column] == None:
            self.board[row][column] = player
            return

打印董事会：

    def print_board(self):
        print "-" * 29
        print "| 0 | 1 | 2 | 3 | 4 | 5 | 6 |"
        print "-" * 29
        for row in range(5,-1,-1):
            s = "|"
            for col in range(7):
                p = self.get_position(row, col)
                if p == None:
                    s += "   |"
                elif p == 1:
                    s += " x |"
                elif p == 2:
                    s += " o |"
                else:
                    # This is impossible if the code is correct, should never occur.
                    s += " ! |"
            print s
        print "-" * 29

我的用法：

b = ConnectFour()

b.play_turn(1, 3)

b.play_turn(1, 3)

b.play_turn(1, 4)

b.match_in_direction(0,3,0,2)

b.print_board()

我当前的输出给我的位置很好...但是它不打印match_in_direction（0,3,0,2）应该是2因为这是多少芯片匹配....任何帮助将是很大的赞赏。

Answer 1

从match_in_direction快速浏览一下，看起来你match == match+1而不是match = match + 1 （或“更好”但match += 1 ）

Answer 2

将此添加到您的测试代码：

f = b.match_in_direction(0,3,0,2) 
print(m)

因为返回语句，你不需要在match_in_direction函数中使用“print match”，并且print board不使用（缺少更好的单词）方向函数中的匹配，因此你必须单独打印出来。

Answer 3

你的match_in_direction函数的格式有点令人困惑，但我认为这是因为这里的拼写错误：

if self.board[row][column] == self.board[nrow][ncolumn]:
    match == match+1

它应该是

match += 1
