Python循环中的套接字程序

我试图做的是从客户端获取一封信，将其发送到服务器，让服务器进行一些更改并将其发送回。然后我希望客户端显示它。但我很难把它变成一个循环。我希望它不断地要求一封信，直到win等于true。我该怎么做？我尝试在服务器端添加一个while循环，但得到了一个关于错误文件描述符的错误。谢谢大家!

客户：

import sys
from socket import *

if sys.argv.__len__() != 3:
  serverName = 'localhost'
  serverPort = 5555
else:
  serverName = sys.argv[1]
  serverPort = int(sys.argv[2])

clientSocket = socket(AF_INET, SOCK_STREAM)


clientSocket.connect((serverName, serverPort))



# Get letter from user
letter = input('Guess a letter: ')

# Sends letter
letterBytes = letter.encode('utf-8')
clientSocket.send(letterBytes)

#Recieves newWord
newWordInBytes = clientSocket.recv(1024)
newWord = newWordInBytes.decode('utf-8')
print(newWord)

clientSocket.close()

服务器：

     import sys

from socket import *

if sys.argv.__len__() != 2:
    serverPort = 5555
else:
    serverPort = int(sys.argv[1])

# This is a welcome socket
serverSocket = socket(AF_INET, SOCK_STREAM)


serverSocket.setsockopt(SOL_SOCKET, SO_REUSEADDR, 1)


serverSocket.bind(('', serverPort))

# Listener begins listening
serverSocket.listen(1)

print("The server is ready to receive")

#Set secret word
word = 'arkansas'
linesForString = ' '    
#Prints out number of letters
for x in word:
    linesForString += '_ '


while 1:
    # Wait for connection and create a new socket
    # It blocks here waiting for connection
    connectionSocket, addr = serverSocket.accept()
    win = ' '
    #Sends lines of words
    linesInBytes = linesForString.encode('utf-8')
    connectionSocket.send(linesInBytes)

    while 1:

        # Receives Letter
        letter = connectionSocket.recv(1024)
        letterString = letter.decode('utf-8')

        win = False 
        while win == False:
            newWord = ' '

            for x in word:
                 if(letterString == x):
                     newWord += x       
                 else:
                     newWord += '_ '

            #Sends newWord
            newWordInBytes = newWord.encode('utf-8')
            connectionSocket.send(newWordInBytes)

            if(newWord == 'Arkansas'):
                win = True
                print('You have won the game')
            else: 
                win = False
        # Close connection to client but do not close welcome socket
        connectionSocket.close()

您没有展示我们可以测试的完整示例。@adrio我刚刚添加了所有代码！非常感谢。您正试图发送给他“但是客户没有在听”。然后，客户端发送一封信，服务器接收并解码该信，然后用丢失的字母组成新词，客户端接收并打印该新词，然后关闭连接。同时，服务器将新词作为内部的

重新生成，而
没有中断，并尝试在一个关闭的连接上再次发送，从而导致该错误。你无法知道他猜到了哪些字母，客户端没有循环，客户端没有听开头的空单词。@Adrio我对python socket编程一无所知，所以你能告诉我如何修复它吗？我无法理解客户端和服务器之间的同步。我将把循环放在客户机端的什么地方？我想如果您在用例中执行类似的操作，您可能会明白这一点：
