【python 打印格式化】python 中的打印美颜机pprint

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。

1、安装pprint包

pip install pprint

2、看看几个例子

# encoding: utf-8

import pprint

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

print student_dict

pprint.pprint(student_dict,width=-1)

# 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。
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=4)
print x
