本文實例為大家分享了python五子棋游戲的具體代碼，供大家參考，具體內容如下
1.項目簡介
在剛剛學習完python套接字的時候做的一個五子棋小游戲，可以在局域網內雙人對戰，也可以和電腦對戰
2.實現思路
局域網對戰
對于局域網功能來說，首先建立連接（tcp），然后每次下棋時將棋子的坐標發送給對方，當接收到坐標后實例化成棋子對象，這個接收時用了select函數，因為pygame需要循環渲染圖片，所以要用非阻塞方式接收消息
select()的機制中提供一fd_set的數據結構，實際上是一long類型的數組， 每一個數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備句柄）建立聯系，建立聯系的工作由程序員完成， 當調用select()時，由內核根據IO狀態修改fd_set的內容，由此來通知執行了select()的進程哪一Socket或文件可讀或可寫，主要用于Socket通信當中
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
電腦對戰
電腦對戰的思路也很簡單，用了應該是最常見的也是最簡單的方法，就是循環遍歷棋盤的每一個點，判斷該點的價值，選取價值最大的點落子，這個需要對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為對方棋子，0為空）
活四（011110）：這時候四顆棋子相連，同時兩端為空，已經阻止不了一方的勝利了，此時價值應該設置最高
死四（011112|10111|11011）：四顆棋子，只有一個地方能形成連五，如果是自己的棋可以贏，是對方的也可以阻止對方贏棋，此時價值次高
就這樣把每種棋型判斷一下，獲得該點的價值，主要代碼如下：
# 判斷每個點的價值 def point_value(pos, white_chesses, black_chesses, identify1, identify2): value = 0 for i in range(1,9): # *1111_ 活四 if get_point(pos, i, 1, white_chesses, black_chesses) == identify1 and \ get_point(pos, i, 2, white_chesses, black_chesses) == identify1 and \ get_point(pos, i, 3, white_chesses, black_chesses) == identify1 and \ 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，要判斷是進攻還是防守，需要兩次遍歷棋盤，獲取進攻時的最大價值和防守的最大價值，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 = ()
# 進攻時
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
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
