Python格式化文件存储---JSON

    Student={

        "name": "ruochen",

        "age": 18,

        "mobile": "18888888888"

    }

- 案例v07
    ```python
    import  json

	# 此时student是一个dict格式内容，不是json

	student={

	    "name": "ruochen",

	    "age": 18,

	    "mobile": "18888888888"

	}

	print(type(student))

	stu_json = json.dumps(student)

	print(type(stu_json))

	print("JSON对象:{0}".format(stu_json))

	stu_dict = json.loads(stu_json)

	print(type(stu_dict))

	print(stu_dict)

    ```

- 案例v08读取文件
    ```python
    import json

	data = {"name":"hahaha", "age":12}

	with open("t.json", 'w') as f:

	    json.dump(data, f)

	with open("t.json", 'r') as f:

	    d = json.load(f)

	    print(d)

    ```
