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)
