一、manage.py

runserver：启动动服务器

二、wsgi.py

python服务器网关接口（不用动就好啦）

三、urls.py

五、创建应用

打开cmd，在untitled的目录下执行dir

然后执行以下代码

新建一个应用(app), 名称叫 blog

python manage.py startapp blog 

　　记得添加到settings.py中

六、migrations数据移植模块

七、admin.py后台控制

八、models.py数据模块，使用ORM模块

九、test.py自动化测试

十、views.py执行响应的代码所在模块，主要代码编辑区

def index(request):

       return HttpRespones('hello')
