Python的subprocess模块在​​Python 2.7中有built-in function这样做。

import subprocess

try:
  mycommand = "ls"
  result = subprocess.check_output(mycommand, shell=True)
  print(result)
except subprocess.CalledProcessError as error:
  # Handle the error
  print("Error: Command exited with code {0}".format(error.returncode))
