套接字服务器//不工作

Question

这是我在 Python 中创建的套接字服务器，但是当我运行它时，它会突出显示 threaded_client 中的 while 循环并出现一个警告框。它说 'invalid syntax'。谁能告诉我发生了什么事。此外，当我注释掉任何内容时，错误只会移到下一行。这是代码：

    import socket
    import sys
    from _thread import *

    host = ''
    port = 5555
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

    try:
        s.bind((host, port))
    except socket.error as e:
        print(str(e))

    s.listen(5)
    print('Waiting...')
    def threaded_client(conn):
        conn.send(str.encode('TYPE HERE\n')

        while True:
            data = conn.recv(2048)
            reply = 'Server output: '+ data.decode('utf-8')
            if not data:
                break
            conn.sendall(str.encode(reply))
        conn.close()

    while True:

        conn, addr = s.accept()
        print('Connected to: '+addr[0]+':'+str(addr[1]))

        start_new_thread(threaded_client,(conn,)

您缺少括号

from thread import *
import socket
import sys

host = ''
port = 5555
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

try:
  s.bind((host, port))
except socket.error as e:
  print(str(e))

s.listen(5)
print('Waiting...')

def threadedClient(conn):
    conn.send(str.encode("Type Here\n"))
    while True:
      data = conn.recv(2048)
      reply = 'Server output: '+ data.decode('utf-8')
      if not data:
        break
      conn.sendall(str.encode(reply))
    conn.close()

while True:

    conn, addr = s.accept()
    print('Connected to: '+addr[0]+':'+str(addr[1]))

    start_new_thread(threaded_client,(conn,))

Socket Server//Not working
