python中获取shell命令输出的方法：

1. 

import subprocess

output = subprocess.Popen(['ls','-l'],stdout=subprocess.PIPE,shell=True).communicate()
print output[0]

 

2.

import commands

return_code, output = commands.getstatusoutput('ls -l')

 

3.

import os

process = os.popen('ls -l') # return file
output = process.read()
process.close()
