json数据格式和读写方法

json数据格式

值用[x1,x2,..]表示,
键值对用{x:,y:}

json读写

json文件与dict

读取json:

import json
f = open('static/data/newsTest.json','rb')
data = json.load(f)

存为json:

with open("../config/record.json","w") as f:
    json.dump(new_dict,f)
    print("加载入文件完成...")

json字符串与dict

dict转字符串:

test_dict = {'bigberg': [7600, {1: [['iPhone', 6300], ['Bike', 800], ['shirt', 300]]}]}
json_str = json.dumps(test_dict)

字符串转dict:

new_dict = json.loads(json_str)
