更多的信息，可以参考python内部的json文档：

python>>> help(json)

或者官方文档：
http://docs.python.org/library/json.html#module-json
下面给出一个使用python解析json的简单例子：

#!/usr/bin/python

import json

#Function:Analyze json script

#Json is a script can descript data structure as xml,

#for detail, please refer to
"http://json.org/json-zh.html".

#Note:

#1.Also,
if you write json script
from python,

#you should use dump instead of load. pleaser refer to
"help(json)".

#json file:

#The file content of temp.json
is:

#{

# "name":"00_sample_case1",

# "description":"an example."

#}

#f = file("temp.json");

#s = json.load(f)

#print s

#f.close

#json string:

s = json.loads('{"name":"test", "type":{"name":"seq", "parameter":["1", "2"]}}')

print s

print s.keys()

print s["name"]

print s["type"]["name"]

print s["type"]["parameter"][1]

-------------------------------------------------------------------------

#coding:utf-8

s='{"total":1,"data":[{"outGuaranteeTime":"","assetsNum":"B50070100007003","cabinet":"H05","deviceModel":"PowerEdge 1950","hostname":"hzshterm1.alibaba.com","logicSite":"中文站","memoryInfo":{"amount":4,"size":8192},"ip":"172.16.20.163","isOnline":true,"useState":"使用中","serviceTag":"729HH2X","cpuInfo":{"amount":2,"masterFrequency":1995,"model":"Intel(R)

import json

def main():

for item in json.loads(s):

print item

if __name__ == '__main__':

main()
