一、基本流程
三子棋游戏实现逻辑如下：
1、创建初始化3*3棋盘；
2、玩家执U子，先进行落子；
3、胜负判定【胜、负、和棋】，若胜负未分，则继续如下
4、电脑执T子，进行落子；
5、胜负判定，若胜负未分，则从步骤2继续执行
二、基本步骤
1、菜单界面
选择1是开始游戏，选择2是退出游戏
def menu():
print('-'*20)
print('1---------------begin')
print('2---------------exit')
print('please select begin or exit')
print('-' * 20)
while(1):
select = input('please input:')
if select == '1':
begin_games()
pass
elif select == '2':
print('exit the game')
break
#pass
pass2、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] = ' '
pass
def print_chess_board(chess_board): #棋盘打印
print('*'+'-'*7+'*'+'-'*7+'*'+'-'*7+'*')
for i in range(MAX_ROW):
print('|'+' '*3+chess_board[i][0]+' '*3+'|'+' '*3+chess_board[i][1]+' '*3+'|'+' '*3+chess_board[i][2]+' '*3+'|')
print('*' + '-' * 7 + '*' + '-' * 7 + '*' + '-' * 7 + '*')
pass
pass
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('please input x:'))
y = int(input('please input y:'))
if(chess_board[x][y] != ' '): #若已被置子，则重新选择坐标
print('This position is already occupied!')
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('This position is beyond the chessboard!')
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] = 'U'
print_chess_board(chess_board)
#return x,y
break
pass
pass4、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；

return5、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。
