实现远程执行系统命令
服务端：

import socket
import os

s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)

s.bind(('127.0.0.1',8080))
s.listen(5)

data_coun,addr = s.accept()
print(data_coun)
while True:
    try:
        data1 = data_coun.recv(1024)
        if not data1:break
        print(data1.decode('utf-8'))
        result = os.system(data1.decode('utf-8'))
        if not result:
            data_coun.send('命令已执行'.encode('utf-8'))
        else:
            data_coun.send('no cmd'.encode('utf-8'))

    except Exception:
        print('服务端：客户端断开了')
        break
data_coun.close()

客户端：

import socket

c = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
print(c)
c.connect(('127.0.0.1',8080))
print(c)
while True:
    cmd = input('请输入命令：').strip()
    if not cmd:continue
    if cmd == 'q':break
    c.send(cmd.encode('utf-8'))
    data = c.recv(1024)
    print(data.decode('utf-8'))

c.close()
