用于无线连接设备的python程序

Question

我从Kalle的视频上看到了这个有趣的想法。它是关于当某人的IP连接到网络时提醒你

import sys
import subprocess
import os
from decouple import config

IP_NETWORK = config('IP_NETWORK')
IP_DEVICE = config('IP_DEVICE')

proc = subprocess.Popen(["ping", IP_NETWORK],stdout=subprocess.PIPE)
while True:
  line = proc.stdout.readline()
  if not line:
    break
  #the real code does filtering here
  connected_ip = line.decode('utf-8').split()[3]

  if connected_ip == IP_DEVICE:
      subprocess.Popen(["say", "Linnea just connected to the network"])

误差

Traceback (most recent call last):
  
File "C:\Users\utkar\Downloads\net-listen.py", line 6, in <module>

好像你忘了设置一个settings.ini。它应该是这样的：

[settings]
IP_Network=YOUR NETWORK IP
IP_DEVICE=YOUR DEVICE IP
