Python下json手法的json在打印查看时，括号和数据都没有展开，查看起来比较困难。
解决方案：
使用json.dumps的separators设置，将数据展开格式化打印。
解决步骤：
data = json.dumps(data, sort_keys=True, indent=4, separators=(‘, ‘, ‘: ‘))
data={
 msgBody:{
   data:
				JSON数据
在日常使用python的过程中，常需要使用json对python的数据进行导出。
JSON数据是JavsScript的子集，专门用于指定结构化的数据，其基于ECMA-262标准，相比于XML，JSON是轻量化的数据交换方式。JSON是以人类更易读的方式传输结构化数据。
 表1 JSON和Python类型之 间的区别 
				1、运用re、json、jsonpath包解析json思路
（1）re：正则表达式，通过json的形式对症下药，写表达式去解析json；
（2）json: 通过json中的json.loads()方法，将str类型转为dict类型，运用python字典的数据结构特点去解析json；
（3）jsonpath：对比与json包，jsonpath可以根据路径去解析json，比较适合用来解析json中带“[ ]”的数据。
2、三种方式的json解析案例
#json数据样式，本文采用带[]的数据样式
				1、Python 有一个名为 json 的内置包，可用于处理 JSON 数据。2、JSON字符串转python对象，使用json.loads()方法(最后的s是字符串的意思)import json
x =  '{ "name":"Bill", "age":63, "city":"Seatle"}'
type(json.loads(x))
# {'name': 'Bill', 'age': 63, 'city': 'Seatle'}注：转换成python对象后，按具体转换后的对象类...
    this_year = 2013
    name = raw_input('please input your name : ')
    age = int(raw_input('please input your age : '))
    sex = raw_input('please input your sex : ')
