In my Django project, the following line throws an ImportError: "No module named elementtree".
from elementtree import ElementTree
However, the module is installed (ie, I can run an interactive python shell, and type that exact line without any ImportError), and the directory containing the module is on the PYTHONPATH. But when I access any page in a browser, it somehow can't find the module, and throws the ImportError. What could be causing this?
