最近在学python，现在假设需要知道这台机器的ip和MAC地址，这个需求用shell和perl很简单就能得到，我这里使用python来实现这个功能，功能比较简单，老鸟可以闪过，下面贴出过程代码

ps.get_list ps.get_nlstr ps.get_paths ps.get_spstr ps.grep
In [3]: ps.grep("inet addr")
Out[3]: SList (.p, .n, .l, .s, .grep(), .fields(), sort() available):
0: inet addr:172.28.19.98 Bcast:172.28.255.255 Mask:255.255.0.0
1: inet addr:172.16.2.165 Bcast:172.16.255.255 Mask:255.255.0.0
2: inet addr:127.0.0.1 Mask:255.0.0.0
In [4]: ps.grep("inet addr").fields(2)
Out[4]: SList (.p, .n, .l, .s, .grep(), .fields(), sort() available):
0: Bcast:172.28.255.255
1: Bcast:172.16.255.255
2: Mask:255.0.0.0
In [5]: ps.grep("inet addr").fields(1)
Out[5]: SList (.p, .n, .l, .s, .grep(), .fields(), sort() available):
0: addr:172.28.19.98
1: addr:172.16.2.165
2: addr:127.0.0.1
In [6]: ps.grep("HWaddr").fields(0,4)
Out[6]: SList (.p, .n, .l, .s, .grep(), .fields(), sort() available):
0: eth0 00:14:85:01:DC:6A
1: eth1 00:0D:88:4A:C6:0D
这里利用的是grep的方法，实现的功能和shell中的awk和sed类似，哈哈，代码很简单吧。。。
