import json
import sys 

data = {"username":"测试","age":16}

#jsondata = json.dumps(data,ensure_ascii=False)
jsondata = json.dumps(data)
print("data convert to json")
print type(json)
text = json.loads(jsondata)
print("json convert to data")

import demjson

data = [ { 'a' : 1, 'b' : 2, 'c' : 3, 'd' : 4, 'e' : 5 } ]
