(Python) TCP socket 통신 채팅 구현

Client.py

from socket import *
import threading
import time


def send(sock):
    while True:
        sendData = input('>>>')
        sock.send(sendData.encode('utf-8'))

    while True:
        recvData = sock.recv(1024)
        print('상대방 :', recvData.decode('utf-8'))


port = 8081

clientSock = socket(AF_INET, SOCK_STREAM)
clientSock.connect(('127.0.0.1', port))

print('접속 완료')

sender = threading.Thread(target=send, args=(clientSock,))
receiver = threading.Thread(target=receive, args=(clientSock,))

sender.start()
receiver.start()

while True:
    time.sleep(1)
    pass

Server.py

from socket import *
import threading
import time

port = 8081

serverSock = socket(AF_INET, SOCK_STREAM)
serverSock.bind(('', port))
serverSock.listen(1)

print('%d번 포트로 접속 대기중...'%port)

connectionSock, addr = serverSock.accept()

print(str(addr), '에서 접속되었습니다.')

receiver.start()

while True:
