    while 1:
        try:
            data = conn.recv(1024)
            if len(data) == 0:
                break
            print('客户端的信息：', data.decode('utf-8'))
            conn.send(data.upper())
        except Exception:
            break
    conn.close()

客户端

import socket

msg = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
msg.connect(('127.0.0.1', 7242))
while 1:
    res = input('请输入信息：').strip()
    if len(res) == 0:
        continue
    msg.send(res.encode('utf-8'))
    data = msg.recv(1024)
    print(data.decode('utf-8'))
msg.close()
