2、初始化棋盘、打印棋盘

三子棋棋盘是3*3的方阵，在python中用列表来进行存储。

chess_board = [[0, 0, 0], [0, 0, 0], [0, 0, 0]]

那么如何将这个存储列表打印出来，成为棋盘呢？

def init_cheaa_board(chess_board): #先对列表进行初始化
    for i in range(MAX_ROW):
        for j in range(MAX_COL):
            chess_board[i][j] = &#39; &#39;
    pass

def print_chess_board(chess_board): #棋盘打印
    print(&#39;*&#39;+&#39;-&#39;*7+&#39;*&#39;+&#39;-&#39;*7+&#39;*&#39;+&#39;-&#39;*7+&#39;*&#39;)
    for i in range(MAX_ROW):
        print(&#39;|&#39;+&#39; &#39;*3+chess_board[i][0]+&#39; &#39;*3+&#39;|&#39;+&#39; &#39;*3+chess_board[i][1]+&#39; &#39;*3+&#39;|&#39;+&#39; &#39;*3+chess_board[i][2]+&#39; &#39;*3+&#39;|&#39;)
        print(&#39;*&#39; + &#39;-&#39; * 7 + &#39;*&#39; + &#39;-&#39; * 7 + &#39;*&#39; + &#39;-&#39; * 7 + &#39;*&#39;)

3、玩家落子

玩家在3*3的棋盘中选择落子的横纵坐标。坐标点需要满足：1、该点在棋盘内；2、该点还未置子。

def player_first(chess_board):
    while(1):
        x = int(input(&#39;please input x:&#39;))
        y = int(input(&#39;please input y:&#39;))
        if(chess_board[x][y] != &#39; &#39;): #若已被置子，则重新选择坐标
            print(&#39;This position is already occupied!&#39;)
            pass
        elif(x >= MAX_ROW or y >= MAX_COL or x < 0 or y < 0): #所选坐标超出棋盘范围，重新选择坐标
            print(&#39;This position is beyond the chessboard!&#39;)
            pass
        else: #若坐标可以落子，则将该坐标置为玩家的棋子U
            chess_board[x][y] = &#39;U&#39;
            print_chess_board(chess_board)
            #return x,y
            break
            pass
    pass

4、电脑落子

电脑落子算法：

4.1、先检查一下棋盘，看电脑已占有棋面中是否已经有两子连成、即将成棋的状态。若已有，则获取可以促成胜利的坐标点，进行落子T；

4.2、若4.1不满足，则再去检查一下棋盘，看玩家已占有棋面中是否已经有两子连成、即将成棋的状态。若已有，则获取玩家即将胜利的坐标点，落子T进行拦截；

4.3、若4.1、4.2均不满足，则在棋面中选择电脑端有利的点进行落子；

A、先判断中心位置[1][1]处是否被占领，若未被占领，则这是最有利点。当占领[1][1]点时，则阻断了玩家的横、纵、正对角线、副对角线四条线路；
B、次有利点则是3*3棋盘的四个角，每占领一个角，则会阻断玩家的三条线路；
C、最后有利的点则是每条边的中心位置，会阻断玩家的两条线路；

5、输赢判定

最终的结果：输、赢、和棋D
判定流程：判断每个横线、纵线、对角线上是否有玩家U或电脑T连成三子的，若有则是该方胜出；当整个棋面都被占满，但玩家和电脑都未成棋时，则说明和棋。

def chess_board_isfull(chess_board):   #判断棋盘是否填充满
    for i in range(MAX_ROW):
        if (&#39; &#39; in chess_board[i]):
            return 0
    return 1
    pass
    
def Win_or_lose(chess_board):
    isfull = chess_board_isfull(chess_board)
    for i in range(MAX_ROW):  #每一列的判断
        if( chess_board[0][i] == chess_board[1][i] == chess_board[2][i]):
            return chess_board[0][i]
            pass
        pass

    for i in range(MAX_ROW):  # 每一行的判断
        if( chess_board[i][0] == chess_board[i][1] == chess_board[i][2]):
            return chess_board[i][0]
            pass
        pass

    if (chess_board[0][0] == chess_board[1][1] == chess_board[2][2]):  # 判断棋盘正对角线
        return chess_board[0][0]

    if (chess_board[0][2] == chess_board[1][1] == chess_board[2][0]):  # 判断棋盘反对角线
        return chess_board[0][2]

    if isfull:
        return &#39;D&#39;  # 经过以上的判断，都不满足(既没赢也没输)，但是棋盘也已经填充满，则说明和棋
    else:
