Using Subprocess.call() To Pass Commands To Execute By Cmd

I am trying to set my IP address to a specific one on a LAN Network. To do this i have tried using the following: import subprocess command='netsh interface ipv4 set address name='

Solution 1:

If you use a string of args you need shell=True:

import subprocess
command="netsh interface ipv4 set address name='Local Area Connection* 4' source=static address=192.168.173.234 mask=255.255.255.0 gateway=192.168.0.1"
subprocess.call(command,shell=True)

You can do it without shell=True which I would recommend by passing a list of args:

import subprocess
command = ['netsh', 'interface', 'ipv4', 'set', 'address', 'name=Local Area Connection* 4', 'source=static', 'address=192.168.173.234', 'mask=255.255.255.0', 'gateway=192.168.0.1']


subprocess.call( command)

Or let shlex.split split the args for you:

import shlex

subprocess.call(shlex.split(command))

using check_call in place of call may also be preferable as call will not raise an error if there is a non-zero exit status where check_call will.

Solution 2:

If there is netsh.exe somewhere in the search path (assuming you are on Windows) then you could pass the command string as is:

import subprocess

subprocess.check_call(command)
