The python module pprint is used for giving proper printing formats to various data objects in python. Those data objects can represent a dictionary data type or even a data object containing the JSON data. In the below example we see how that data looks before applying the pprint module and after applying it.

import pprint

student_dict = {''Name'': ''Tusar'', ''Class'': ''XII'', 
     ''Address'': {''FLAT '':1308, ''BLOCK '':''A'', ''LANE '':2, ''CITY '': ''HYD''}}

print student_dict
print "n"
print "***With Pretty Print***"
print "-----------------------"
pprint.pprint(student_dict,width=-1)

When we run the above program, we get the following output −

{''Address'': {''FLAT '': 1308, ''LANE '': 2, ''CITY '': ''HYD'', ''BLOCK '': ''A''}, ''Name'': ''Tusar'', ''Class'': ''XII''}


***With Pretty Print***
-----------------------
{''Address'': {''BLOCK '': ''A'',
             ''CITY '': ''HYD'',
             ''FLAT '': 1308,
             ''LANE '': 2},
 ''Class'': ''XII'',
 ''Name'': ''Tusar''}

Handling JSON Data

Pprint can also handle JSON data by formatting them to a more readable format.

import pprint

emp = {"Name":["Rick","Dan","Michelle","Ryan","Gary","Nina","Simon","Guru" ],
   "Salary":["623.3","515.2","611","729","843.25","578","632.8","722.5" ],   
   "StartDate":[ "1/1/2012","9/23/2013","11/15/2014","5/11/2014","3/27/2015","5/21/2013",
      "7/30/2013","6/17/2014"],
   "Dept":[ "IT","Operations","IT","HR","Finance","IT","Operations","Finance"] }

x= pprint.pformat(emp, indent=2)
print x
   

When we run the above program, we get the following output −

{ ''Dept'': [ ''IT'',
            ''Operations'',
            ''IT'',
            ''HR'',
            ''Finance'',
            ''IT'',
            ''Operations'',
            ''Finance''],
  ''Name'': [''Rick'', ''Dan'', ''Michelle'', ''Ryan'', ''Gary'', ''Nina'', ''Simon'', ''Guru''],
  ''Salary'': [ ''623.3'',
              ''515.2'',
              ''611'',
              ''729'',
              ''843.25'',
              ''578'',
              ''632.8'',
              ''722.5''],
  ''StartDate'': [ ''1/1/2012'',
                 ''9/23/2013'',
                 ''11/15/2014'',
                 ''5/11/2014'',
                 ''3/27/2015'',
                 ''5/21/2013'',
                 ''7/30/2013'',
                 ''6/17/2014'']}
