python技巧 namedtuple

python的namedtuple可以创建一个带字段名的元祖和一个带名字的类

In [1]: from collections import namedtuple
   ...:
   ...: nginx=namedtuple('nginx',['active','accepts','handled','requests','reading','writing','waiting'])
   ...:

In [2]: get_nginx=nginx(1,2,3,4,11,111,22)

In [3]: get_nginx.active
Out[3]: 1

In [4]: get_nginx
Out[4]: nginx(active=1, accepts=2, handled=3, requests=4, reading=11, writing=111, waiting=22)In
