這篇文章主要為大家詳細(xì)介紹了python小項(xiàng)目之五子棋游戲，文中示例代碼介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了python五子棋游戲的具體代碼，供大家參考，具體內(nèi)容如下

1.項(xiàng)目簡(jiǎn)介

在剛剛學(xué)習(xí)完python套接字的時(shí)候做的一個(gè)五子棋小游戲，可以在局域網(wǎng)內(nèi)雙人對(duì)戰(zhàn)，也可以和電腦對(duì)戰(zhàn)

2.實(shí)現(xiàn)思路

局域網(wǎng)對(duì)戰(zhàn)

對(duì)于局域網(wǎng)功能來(lái)說(shuō)，首先建立連接（tcp），然后每次下棋時(shí)將棋子的坐標(biāo)發(fā)送給對(duì)方，當(dāng)接收到坐標(biāo)后實(shí)例化成棋子對(duì)象，這個(gè)接收時(shí)用了select函數(shù)，因?yàn)閜ygame需要循環(huán)渲染圖片，所以要用非阻塞方式接收消息

select()的機(jī)制中提供一fd_set的數(shù)據(jù)結(jié)構(gòu)，實(shí)際上是一long類型的數(shù)組，每一個(gè)數(shù)組元素都能與一打開的文件句柄（不管是Socket句柄，還是其他文件或命名管道或設(shè)備句柄）建立聯(lián)系，建立聯(lián)系的工作由程序員完成，當(dāng)調(diào)用select()時(shí)，由內(nèi)核根據(jù)IO狀態(tài)修改fd_set的內(nèi)容，由此來(lái)通知執(zhí)行了select()的進(jìn)程哪一Socket或文件可讀或可寫，主要用于Socket通信當(dāng)中

主要代碼如下：

# 接收cli的消息
if is_people:
 rs, ws, es = select.select(inputs, [], [], 0)
  for r in rs:
    if r is tcpclisock:
    try:
     data = r.recv(BUFSIZ)
      islink = True
      print(data.decode('utf8'))
      if data.decode('utf8') == 'again':
       is_recieve1 = True
      if data.decode('utf8') == 'yes':
       is_playagain = True
       is_play = True
      if data.decode('utf8') == 'no':
       is_recieve2 = True
       islink = False
      if not is_play and not result:
       me = storn.Storn_Black(eval(data))
       black_chesses.append(me)
        chesses.append(me)
       is_play = True
     except error:
      islink = False

電腦對(duì)戰(zhàn)

電腦對(duì)戰(zhàn)的思路也很簡(jiǎn)單，用了應(yīng)該是最常見的也是最簡(jiǎn)單的方法，就是循環(huán)遍歷棋盤的每一個(gè)點(diǎn)，判斷該點(diǎn)的價(jià)值，選取價(jià)值最大的點(diǎn)落子，這個(gè)需要對(duì)五子棋的棋型有一定了解，這里介紹幾種常見的棋型（約定1為己方棋子，2為對(duì)方棋子，0為空）

活四（011110）：這時(shí)候四顆棋子相連，同時(shí)兩端為空，已經(jīng)阻止不了一方的勝利了，此時(shí)價(jià)值應(yīng)該設(shè)置最高
死四（011112|10111|11011）：四顆棋子，只有一個(gè)地方能形成連五，如果是自己的棋可以贏，是對(duì)方的也可以阻止對(duì)方贏棋，此時(shí)價(jià)值次高

就這樣把每種棋型判斷一下，獲得該點(diǎn)的價(jià)值，主要代碼如下：

# 判斷每個(gè)點(diǎn)的價(jià)值
def point_value(pos, white_chesses, black_chesses, identify1, identify2):
 value = 0
 for i in range(1,9):

   get_point(pos, i, 4, white_chesses, black_chesses) == identify1 and \
   get_point(pos, i, 5, white_chesses, black_chesses) == 0:
   value += 40000

電腦選擇落子位置時(shí)，要判斷是進(jìn)攻還是防守，需要兩次遍歷棋盤，獲取進(jìn)攻時(shí)的最大價(jià)值和防守的最大價(jià)值，主要代碼如下：

# 電腦選取落子的位置
def ai(white_chesses, black_chesses, chesses):
 value = max1 = max2 = 0
 pos1 = pos2 = ()
 # 進(jìn)攻時(shí)
 for i in range(0,15):
   row = 28 + i * 40
   for j in range(0,15):
    col = 28 + j * 40
    pos = (row,col)
   if is_empty(pos, chesses):
     continue
    value = point_value(pos, white_chesses, black_chesses, 1, 2)
    if value > max1:
     max1 = value
     pos1 = (row,col)
 
  # 防守時(shí)
  for i in range(0,15):
   for j in range(0,15):
    row = 28 + i * 40
    col = 28 + j * 40
    if is_empty((row,col), chesses):
     continue
   value = point_value((row,col), white_chesses, black_chesses, 2, 1)
    if value > max2:
     max2 = value
     pos2 = (row,col)
  if max1 > max2:
   return pos1
  else:
   return pos2
