服务端代码

import socketphone=socket.socket(socket.AF_INET,socket.SOCK_STREAM)phone.bind(('127.0.0.1',8000))phone.listen(5)while True:    conn,client=phone.accept()    while True:        try:            data=conn.recv(1024)            print('客户端数据: ', data)            conn.send(data.upper())        except ConnectionResetError:            break    conn.close()phone.close()

客户端代码:

import socketphone=socket.socket(socket.AF_INET,socket.SOCK_STREAM)phone.connect(('127.0.0.1',8000))while True:    msg=input('>>:').strip()    phone.send(msg.encode('utf-8'))    data=phone.recv(1024)    print(data.decode('utf-8'))phone.close()
