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) Xeon(R) CPU           E5405  @ 2.00GHz","coreNum":8,"l2CacheSize":6144},"cabinetPositionNum":"","buyTime":"2009-06-29","manageIp":"172.31.58.223","idc":"杭州德胜机房","responsibilityPerson":"张之诚"}],"errorMsg":"","isSuccess":true}'

import json
def main():
    for item in json.loads(s):
        print item

if __name__ == '__main__':
    main()
