Python对象和JSON对象的相互转化

#coding:utf-8import json# 一、Python对象和JSON字符串可以相互转化#1.Python对象转化成JSONstudent={    'name':'gavin',    'age':18}print repr(json.dumps(student))#把JSON字符串转化成Python对象s = '{"age":18, "name": "gavin"}'print json.loads(s).get('age')# 二、Python对象和JSON文件可以相互转化# 1.把Python对象转化为JSON文件f = open('student.json','w')json.dump(student,f)f.close()#2.把JSON文件转化成Python对象f = open('student.json')print json.load(f).get('name')
