How do I replicate “from module import class” with __import__() or django.utils.importlib?

Question

I want to import a class from python module. The module contains multiple classes and which one I need is determined by a string at runtime.

Edit: I'm using python 2.6.5, django 1.3.

Answer 1

明智地使用getattr() 。

Answer 2

MyClass = getattr(mymodule, myclass_name)

Answer 3

或者导入 （module，globals（），locals（），['classname'，]， - 1）
