Django的开发遵循MTV模式（models, templates, views），views.py负责执行操作，models.py负责数据处理（如数据库连接），templates目录下存放网页的模板

## **       5、在templates下新建一个index.html文件** ##

<!DOCTYPE html>
    <html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>Title</title>
    </head>
    <body>
        <h2>hello world</h2>
    </body>
    </html>

##       ** 6、编写views.py文件，定义访问这个index.html文件的操作** ##
