Python 之json模块

一、代码

import json

if __name__ == '__main__':
    str1 = '{"username": "Yang", "password": "12345"}'
    #json解析
    json_obj = json.loads(str1)
    print(json_obj.get('username'))
    print(json_obj.get('password'))

    str2 = '[{"username": "Yang", "password": "12345"}, {"username": "admin", "password": "admin123"}]'
    json_obj = json.loads(str2)
    for item in json_obj:
        print(item) #{'username': 'Yang', 'password': '12345'}
    
    #转json字符串
    arr = [{"username": "Yang", "password": "12345"}, {"username": "admin", "password": "admin123"}]
    json_str = json.dumps(arr)
    print(type(json_str)) #<class 'str'>
