Question

我正在尝试创建一个python程序，当它打开时充当客户端并检测周围任何服务器的存在，持续15秒。如果它找不到任何东西，它会将自己升级到服务器并将自己的ip广播为HOST。 iterateserver（）和iterateclient（）已经在外部定义。

s = socket(AF_INET, SOCK_STREAM)
s.setsockopt(SOL_SOCKET, SO_REUSEADDR, 1)
PORT = 37885

try:
    s.settimeout(15)
    s.connect(('', PORT))
    print (HOST)
    for j in range(M):
        h=iterateclient()

except:
    print "\n"+"Switching to server configuration"+"\n"
    addr_list = []                                      #list of client addresses 
    s.bind(('', PORT)) 
    s.listen(0)
    print 'Waiting for client...' 
    for i in range(procno - 1):                         #Connects to all clients
        conn, addr = s.accept(1024)                   #Accepts connection from client 
        print 'Connected by', addr 
        if addr not in addr_list:
            addr_list.append(addr)                      #Adds address to address list
    start_time = time.time()
    for j in range(M):
        h=iterateserver()
    time_taken = time.time() - start_time
    print 'Time taken is ', time_taken, 'seconds.'
    plt.figure()
    plt.plot(x2,f)
    plt.show()

显示以下错误： -

$ python auto_burger.py 

Switching to server configuration

Traceback (most recent call last):
  File "auto_burger.py", line 34, in <module>
    s.bind(('', PORT)) 
  File "/usr/lib/python2.7/socket.py", line 228, in meth
    return getattr(self._sock,name)(*args)
