python json 序列号/反序列化

json格式与字符串格式相互转换：

序列化  json.loads()

反序列化  # json.dumps(obj,ensure_ascii=True,indent=None,sort_keys=False)

import json

# json_str='{"name":"Felix","age":18}'

# print(json_str,type(json_str))

# load_data=json.loads(json_str)

# print(load_data,type(load_data))

# with open('felix.json','r',encoding='utf-8') as f:

#    load_data=json.load(f)

#    print(load_data,type(load_data))

#

# json.dumps(obj,ensure_ascii=True,indent=None,sort_keys=False)

data={

"name":"Felix",

    "age":18,

    "hobby": ['运动','妹子'],

    "friends": [

{

"name":"刘德华"

        },

        {

"name":"梁朝伟"

        }

]

}

json_str=json.dumps(data)

print(json_str)

print(json.dumps(data,ensure_ascii=False))

print(json.dumps(data,ensure_ascii=False,indent=4))

print(json.dumps(data,ensure_ascii=False,indent=4,sort_keys=True))
