導入在Python包並不一定自動導入任何子封裝/模塊它。當您執行import django.contrib.gis.gdal時，它在gdal目錄中運行__init__.py;它取決於該文件，不管它是否通過import libgdal以便通過gdal可用。在這種特殊情況下，gdal進口（等等）從libgdalgdal_full_version功能到其本身，而不是libgdal作爲一個整體，所以你可以這樣做：

>>> import django.contrib.gis.gdal 
>>> print django.contrib.gis.gdal.gdal_full_version() 
GDAL 1.6.3, released 2009/11/19 

或將明確就函數實際上是定義在那裏，你可以這樣做：

>>> import django.contrib.gis.gdal.libgdal 
>>> print django.contrib.gis.gdal.libgdal.gdal_full_version() 
GDAL 1.6.3, released 2009/11/19
