Two parts:
Shell
netstat | python read_netstat.py
Python read_netstat.py
import sys
variable = sys.stdin.read()
That will read the output from netstat into a variable.
这将把netstat的输出读入变量。

It is possible. See:
有可能的。看到:
http://docs.python.org/library/subprocess.html#replacing-bin-sh-shell-backquote
In Python 2.4 and above:
在Python 2.4及以上版本中:
from subprocess import *
x = Popen(["netstat", "-x", "-y", "-z"], stdout=PIPE).communicate()[0]

Take a look at the subprocess module. It allows you to start new processes, interact with them, and read their output.
看一下子进程模块。它允许您启动新进程,与它们交互并读取其输出。
In particular see the section Replacing /bin/sh shell backquote:
特别参见Replacing / bin / sh shell反引号部分:
output = Popen(["mycmd", "myarg"], stdout=PIPE).communicate()[0]
