from json import load, loads, dumps, dump
from json import load


# 将Python 字典转化为json字符串
def dumps_func(dic: dict):
    print(dumps(dic))


# 将Python对象序列为上下文管理器对象
def dump_func(dic: dict):
    dump(dic, open('demo.txt', "w"))
    with open('demo.txt', "r") as  ff:
        print(ff.read())


# 将Python对象序列为json字符串
def load_func(string: str):

# 将json字符串反序列为 Python对象
def loads_func(string: str):

# 将文件对象反序列为 Python对象
def load_func():
    with open("demo.txt", mode='r') as f:
