#json.dump  json.load   用于文件的存储和读取  简化了文件的读取操作
dict_name = {"name": "yaoming", "age": 18}
with open("text.txt", "w+", encoding="utf-8") as f2:
    json.dump(dict_name,f2)           #直接序列化写入
    f2.seek(0)
    data_load_read = json.load(f2)         #读取出来再还原原来存储的类型
    print(data_load_read, type(data_load_read))
    
# {'name': 'yaoming', 'age': 18} <class 'dict'>
