我认为问题是将json字符串转换为python字典，您可以使用json模型。
下面是参考代码，json.loads是关键方法：
#!/usr/bin/python3.6
# -*- coding: utf-8 -*-
import json
# data.txt: full json text
f = open("./data.txt", 'r')
full_txt = f.read()
f.close()
# decode json text to python dictionary
full_txt = json.loads(full_txt, encoding='utf-8', strict=False)
# do some thing just like operate python dictionary
for k,v in full_txt.items():
