在python中将变量传递给命令

Question

i'm writing a python script to execute shell command, and i'm taking arguments and i want to pass the value of that to the command

#!/usr/bin/env python

import commands
import subprocess
import sys

command = commands.getoutput('fs_cli -x "sofia profile external restart"')

this code works fine

when i try to take the argument and pass to command it fails

command = commands.getoutput('fs_cli -x "sofia profile" + sys.argv[1] + " restart"')

supp folks

Answer 1

你应该写：

command = commands.getoutput('fs_cli -x "sofia profile ' + sys.argv[1] + ' restart"')

Answer 2

看看argparse和subprocess 。

Answer 3

One of the way to do this is to convert your command that you want to execute into string and then execute it as eval()

example : eval(expression/command in string)
