利用pprint模块名目化数据

Python的pprint模块中利用的名目化可以凭据一种名目正确的显示数据, 这种名目即可被理会器理会, 又很易读. 输出生存在一个单行内, 但假如有须要, 在支解多行数据时也可利用缩进暗示.

import sys
import pprint
pprint.pprint(sys.path)

运行功效：

['',
 '/usr/local/lib/python27.zip',
 '/usr/local/lib/python2.7',
 '/usr/local/lib/python2.7/plat-linux2',
 '/usr/local/lib/python2.7/lib-tk',
 '/usr/local/lib/python2.7/lib-old',
 '/usr/local/lib/python2.7/lib-dynload',
 '/usr/local/lib/python2.7/site-packages']

假如仅仅想得到数据而不是输出数据也可以用pformat

import sys
import pprint
str = pprint.pformat(sys.path)
print str

运行功效：

['',
 '/usr/local/lib/python27.zip',
 '/usr/local/lib/python2.7',
 '/usr/local/lib/python2.7/plat-linux2',
 '/usr/local/lib/python2.7/lib-tk',
 '/usr/local/lib/python2.7/lib-old',
 '/usr/local/lib/python2.7/lib-dynload',
 '/usr/local/lib/python2.7/site-packages']

运行功效是一样的~~
