简单的socket例子

客户端代码（client.py）

import socket

client = socket.socket()
client.connect(('localhost',8080))

while True:
    data = input('>>>')
    client.send(data.encode('utf-8'))#data必须为字节序列

    data = client.recv(1024).decode()
    print('>>>',data)

client.close()

服务端代码（server.py）

import socket

server = socket.socket()
server.bind(('localhost',8080))
server.listen()

while True:
    conn,addr = server.accept()

    while True:
        data = conn.recv(1024)
        if not data:
            print('the client is lost!!!')
            break
        print('>>>',data.decode())
        data = input('>>>').encode('utf-8')
        conn.send(data.encode('utf-8'))

server.close()
