Python implements a method to get command line output

This article is an example of an Python implementation that captures command-line output. To share for your reference, specific as follows:

Python gets the command line output and filters the results to find what you need!

Here's an example of getting the native MAC address and IP address!

# coding: GB2312
import os, re
# execute command, and return the output
def execCmd(cmd):
  r = os.popen(cmd)
  text = r.read()
  r.close()
  return text
# write "data" to file-filename
def writeFile(filename, data):
  f = open(filename, "w")
  f.write(data)
  f.close()
#  Acquisition computer MAC The address and IP address 
if __name__ == '__main__':
  cmd = "ipconfig /all"
  result = execCmd(cmd)
  pat1 = "Physical Address[\. ]+: ([\w-]+)"
  pat2 = "IP Address[\. ]+: ([\.\d]+)"
  MAC = re.findall(pat1, result)[0]    #  find MAC
  IP = re.findall(pat2, result)[0]    #  find IP
  print("MAC=%s, IP=%s" %(MAC, IP))

Operation results:

E:\Program\Python>del.py
MAC=00-1B-77-CD-62-2B, IP=192.168.1.110
E:\Program\Python>
