Python学习总结10：获取shell输出结果

Python中获取shell命令的输出结果的常见方法如下几种：

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')

可返回状态与调用的shell命令的输出结果

3.

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