Python解析Json

JSON问题

目标解析对象数组的对象如下：

24 class Question:
25 
26     def __init__(self, qid, item, options, answer, point, analysis):
27         self.qid = qid
28         self.item = item
29         self.option = Option(options)
30         self.answer = answer
31         self.point = point
32         self.analysis = analysis
33 
34     def display(self):
35         print
36         str(self.qid) + ":" + str(self.item) + str(self.answer) + str(self.point) + str(self.analysis)
37         self.option.display()
38 

对象转JSON

import json

# 这是复杂对象的json转换，因为对象里面还有对象
# quesOut是Question的一个实例
json_out = json.dumps(quesOut, default=lambda o: o.__dict__, sort_keys=True, indent=4, ensure_ascii=False)
             print json_out

JSON转对象

本地打开Json文件

24 def main(fileName):
25     with open(fileName,'r') as f:
26         load_json = json.load(f)
27         question_size = load_json['size']
28         for i in range(question_size):
29             #print load_json['res']['questions'][i]
30             parseOneJson(load_json['res']['questions'][i])
31 
32         print load_json['res']['questions'][1]['questionType']
