关于socket模块的.accept（）返回值的问题

Question

我对python非常陌生，在使用socket模块设置TCP连接时遇到了一个问题。以下是我的部分代码：

clients = {}
addresses = {}

HOST = ''
PORT = 33000
BUFSIZ = 1024
ADDR = (HOST, PORT)
SERVER = socket(AF_INET, SOCK_STREAM)
SERVER.bind(ADDR)

def accept_incoming_connections():
    while True:
       client, client_address = SERVER.accept()
       print ("The Client is: ")
       print (client.raddr)
       print ("%s:%s has connected." % clinet_address)
       client.send(bytes("Greetings from the cave!" + "Now type your name and press enter!"),"utf8")
       addresses[client] = client_address
       Thread(target = handle_client, args = (client,)).start()

代码如下：

^{pr2}$

我试图让变量“client_address”存储客户机的IP地址，但在运行它时，结果却一无所获。这个变量根本没有赋值。在我检查了“client”中存储的值后，我发现：

'<socket.socket fd=4, family=AddressFamily.AF_INET, type=SocketKind.SOCK_STREAM, proto=0, laddr=('10.146.0.2', 33000), raddr=('104.38.51.137', 62283)>'

在“raddr”部分，我找到了我的客户端IP地址和端口，这是为什么？我记得accept（）函数有两个返回阀。如果真的只有一个返回值，我应该如何从这个返回阀提取客户端IP和端口？在

如果需要，我也会在这里发布我的客户代码：

import socket               # Import Socket module
import time

myname = input ("input you username>>")
s = socket.socket()         # Create a Socket object
ip= "35.200.59.31" 
port = 33000                # setup port number

s.connect((ip, port))
s.send(bytes(myname, encoding="utf-8"))
print (s.recv(1024))
username=str(input("input user name>>"))
s.send(bytes(username))

flag=True
while flag:
    signal=s.recv(1024)
    if signal == (bytes("xxx", encoding = "utf-8")):
        tosend=(input(">>>"))
        s.send(bytes(tosend))
        print (">>",tosend)
        if tosend=="quit":
            flag = False
    else :
        print (">>>",signal)
s.close()

谢谢大家！我的问题基本解决了。以下是固定代码：

clients = {}
addresses = {}

HOST = ''
PORT = 33000
BUFSIZ = 1024
ADDR = (HOST, PORT)
SERVER = socket(AF_INET, SOCK_STREAM)
SERVER.bind(ADDR)

def accept_incoming_connections():
    while True:
       client, client_address = SERVER.accept()
       print ("The Client address is: ")
       print (client_address[0])
       print (str(client_address[0]) + " has connected.")
       client.send(bytes("Greetings from the cave!" + "Now type your name and press enter!",'utf8'))
       addresses[client] = client_address[0]
           Thread(target = handle_client, args = (client,)).start()

它现在可能还存在一些问题（尽管现在编译仍然会有一些问题）。再次感谢！在
