This is what I can't get to work in my case. Here's the setup: directory testpkg containing three files: 1. an empty __init__.py 2. a testimport.py which has: from testpkg.testimported import A a = A() print type(a) 3. a testimported.py which has: class A(): pass When I run python testimport.py I get: Traceback (most recent call last): File "testimport.py", line 1, in from testpkg.testimported import A ImportError: No module named testpkg.testimported However, I thought I was doing what the doc describes for intra package imports. What am I missing? Or is the problem simply that I do not have subpackages? -- Gerald Britton
