pprint and pformat for data formatting in Python

Many times we need to format data. Have you ever had a headache with data formatting in python? pprint will help you a lot

The formatting used in the pprint module can correctly display the data in a format that can be parsed by the parser and is easy to read. The output is saved in a single line, but If necessary, indentation can also be used when splitting multiple lines of data.

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

Running results:

['',

'/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']

If you just want to get data instead of outputting data, you can also use pformat

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

The output result is the same as above
