美化打印数字
美化打印数字详细操作教程
python模块pprint用于为python中的各种数据对象提供正确的打印格式。 这些数据对象可以表示字典数据类型，甚至可以表示包含JSON数据的数据对象。 在下面的示例中，我们将看到在应用pprint模块之前和应用它之后数据的输出格式。

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)
当运行上面的程序时，得到以下输出 -

{'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'}
处理JSON数据
Pprint还可以通过将JSON数据格式化为更易读的格式来处理它们。

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
当运行上面的程序时，得到以下输出 -
