1、主要文件

MyDjango项目里包含MyDjango文件夹和manage.py文件，而MyDjango文件夹又包含5个py文件。项目的每个文件说明如下：

(1)manage.py

命令行工具，内置多种方式与项目进行交互。在命令提示符窗口下，将路径切换到MyDjango项目并输入python manage.py help，可以查看该工具的指令信息。

(2）init.py

初始化文件，一般情况下无须修改。默认内容为空。

(3)asgi.py

用于启动异步通信服务，比如实现在线聊天等异步通信功能

(4)settings.py

项目的配置文件，项目所有功能都需要在该文件中进行配置
