Question

我是Python的新手，我正在尝试设置一个脚本来检查本地网络上特定wifi连接的IOT设备的状态。

本质上，脚本会获取我想要检查的mac硬件ID; ping网络触发ARPs;搜索arp-a的响应，查找相关的mac ID，如果成功找到，则打印出日期和时间。

两个问题 - 1）目前我正在搜索2个mac地址但是前进它更可能是20个。如何修改我的detect_mac函数以获取二维数组（或类似）并循环遍历结果是为了避免重复if any(address in str_output for address in input_address_list1):行20次。

2）如果我让这个脚本不断运行（它在运行之间有10分钟的计时器），这个python最终会崩溃吗？是否有某种垃圾收集，日志溢出等我需要考虑？

import pdb, os
import subprocess
import re
import time
from subprocess import Popen, PIPE, DEVNULL

lower=1
upper=25
MAC_address_list1 = ["58:e2:zz:xx:28:d7"]
MAC_address_list2 = ["08:05:xx:zz:75:c5"]
MAC_address_list3 = ["##:##:##:##:##:##"]
MAC_address_list4 = ["##:##:##:##:##:##"]
p = {}

# Get The Current Date and Time
def getdatetime():
    import time
    return time.strftime("%H:%M %d/%m/%Y ")

def detect_mac(input_address_list1, input_address_list2):
    # Assign list of devices on the network to "output"
    output = subprocess.check_output("arp -a", shell=True)

    str_output = output.decode("utf-8")   

    if any(address in str_output for address in input_address_list1):
        print(getdatetime() + str(input_address_list1))

    if any(address in str_output for address in input_address_list2):
        print(getdatetime() + str(input_address_list2))

    #sleep 10 minutes
    time.sleep(600)
    return True


while 1:
    # ping all IPs in range to make ARP available
    for i in range(lower,upper):
        ip = "192.168.1.%d" % i
        p[ip] = Popen(['ping', '-n', '-w5', '-c3', ip], stdout=DEVNULL)

    detect_mac(MAC_address_list1, MAC_address_list2)

我当然可以回答第1点）：

import pdb, s
import subprocess
import re
import time
from subprocess import Popen, PIPE, DEVNULL

lower=1
upper=25
MAC_address_list1 = ["58:e2:zz:xx:28:d7"]
MAC_address_list2 = ["08:05:xx:zz:75:c5"]
MAC_address_list3 = ["##:##:##:##:##:##"]
MAC_address_list4 = ["##:##:##:##:##:##"]

MAC_addresses = ([MAC_address_list1],[MAC_address_list2])

[...]

def detect_mac(input_address_list):
  # Assign list of devices on the network to "output"
  output = subprocess.check_output("arp -a", shell=True)

  str_output = output.decode("utf-8")   

  for address_list in input_address_list:

    if any(address[0] in str_output for address in address_list):
        print(getdatetime() + str(address_list))



  #sleep 10 minutes
  time.sleep(600)
  return True

Python 2D数组和循环
