1、客户端和服务器聊天，可以一直聊天，直到一方发送’拜拜’。然后就可以和下一个人一直聊

server.py

import socket


def creat_server():
    server = socket.socket()
    server.bind(('10.7.153.127', 8081))
    server.listen(512)

    while True:
        connect,addr = server.accept()
        while True:
            recv_message = connect.recv(1024)
            print(recv_message.decode(encoding='utf-8'))
            if recv_message.decode(encoding='utf-8')=='拜拜':
                break
            message = input('服务器：')
            connect.send(message.encode())
            if message == '拜拜':

                break
    connect.close()


if __name__ == '__main__':
    creat_server()

client.py

import socket
def creat_client():
    client = socket.socket()
    client.connect(('10.7.153.127', 8081))

    while True:
        message = input('客户端：')
        client.send(message.encode())
        if message == '拜拜':

            break
        recv_message = client.recv(1024)
        print(recv_message.decode(encoding='utf-8'))
        if recv_message.decode(encoding='utf-8') == '拜拜':
            break
    client.close()

if __name__ == '__main__':
    creat_client()

2、下载网络图片（https://ss1.bdstatic.com/70cFuXSh_Q1YnxGkpoWK1HF6hhy/it/u=2808438283,4249462766&fm=26&gp=0.jpg）到本地

import requests
url = 'https://ss1.bdstatic.com/70cFuXSh_Q1YnxGkpoWK1HF6hhy/it/u=2808438283,4249462766&fm=26&gp=0.jpg'
response = requests.get(url)
image = response.content
with open('./files/03.jpg', 'wb') as f:
    f.write(image)

结果：
