python json操作

1. 读取jsom

import json
line_dic = json.loads(line)#转成json
line_dic[‘word’] #读取具体的元素

2.写json

annotation = {“tid”: “”, “title”: “”, “value”: “”}#定义字典，方便转化json
annotation[‘title’]=‘1’
annotation[‘tid’] = ‘主题’
annotation[‘value’] = ’具体值‘
with open(“E:/test.json”,“w”,encoding=‘utf-8’) as f:
json.dump(annotation,f,ensure_ascii=False)

3.json写入中文

json.dump(annotation,f,ensure_ascii=False)#防止写入的是ascii码，不是中文
