从包中实例化导入的“类”时,如何避免使用package.class()声明?

我对Python还不太熟悉,所以我仍然沉浸在整个名称空间中。 我创建了一个包,其中包含in it文件,还有一个classname.py文件,显然包含了这个类。 例如: 从降落伞导入容器,发射器

我试图直接实例化类容器,但它给了我一个错误,所以我不得不将其作为Container.Container()来实例化。我怎样才能避免这样做呢? 基本上,我想做的是从包中导入一个类,避免键入包名和/或文件名。 提前谢谢,如果问题不够清楚,请告诉我。

更新 我的结构是: -- 初始 .py年

-- container.py
    Serves as a controller, i'd say, instancing, calling and glueing all the other parts    together.

-- sparkles.py
    Has two classes: Sparkle and Sparkles. Sparkle is a single element, with only one    property so far, and Sparkles serves as a collection.  Sparkles() belongs to the Emitter, and Sparkle() belongs to Sparkles().

-- emitter.py 
    Emitter could be seen as the user entity. It has a name and an uid, it belongs to a Container and the Container belongs to it.

现在,我从包外部调用Container并传递一些参数,容器实例并根据需要分发参数。
