Python中数据名目化的pprint和pformat

许多时候我们需要对数据举办名目化，你有没有对python中的数据名目化感想头疼呢？pprint会帮你很大的忙

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/python2.7/site-packages/MySQL_python-1.2.3-py2.7-linux-x86_64.egg',

'/usr/local/lib/python2.7/site-packages/web.py-0.36-py2.7.egg',

'/usr/local/lib/python2.7/site-packages/SQLAlchemy-0.7.5-py2.7-linux-x86_64.egg',

'/usr/local/lib/python2.7/site-packages/thrift-0.8.0-py2.7-linux-x86_64.egg',

'/usr/local/lib/python2.7/site-packages/setuptools-0.9.8-py2.7.egg',

'/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',

'/usr/local/lib/python2.7/site-packages/PIL']

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

输出功效和上面是一样的
