很多时候我们需要对数据进行格式化,你有没有对python中的数据格式化感到头疼呢?pprint会帮你很大的忙
pprint模块中使用的格式化可以按照一种格式正确的显示数据,这种格式即可被解析器解析,又很易读. 输出保存在一个单行内,但如果有必要,在分割多行数据时也可使用缩进表示.
# @param Python中数据格式化的pprint和pformat
# @author 编程之家 jb51.cc|512Pic.com
import sys
import pprint
pprint.pprint(sys.path)
# End www.jb51.cc
运行结果:
['',
'/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/lib-dynload',
'/usr/local/lib/python2.7/site-packages',
'/usr/local/lib/python2.7/site-packages/PIL']
如果仅仅想获得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
# End www.jb51.cc
输出结果和上面是一样的
