Python包管理：按类而非文件进行导入的最佳实践

Say I have the following file structure:

假设我有以下文件结构:

app/
  app.py
  controllers/
    __init__.py
    project.py
    plugin.py

If app/controllers/project.py defines a class Project, app.py would import it like this:

如果app / controllers /项目。py定义了一个类项目，app.py会这样导入:

from app.controllers.project import Project

I'd like to just be able to do:

我想做的是:

from app.controllers import Project

How would this be done?

怎么做呢?
