adding both contrib and test in your example to the path is indeed bad since
as far as Python is concerned contrib.test and test refer to two separate
The __init__.py inside of the test package contains "from test.other import
something"? It can simply be
from other import something
which would bring something into test. This won't work in more complicated
If mod2.py from package2 needs to reference something from package1 it had
no choice traditionally but to refernece package1 as test.package1 (which
causes exactly the problems you describe). This is the reason relative
imports were added but it does require patching the library in question. I
don't think there is any way around this other than:
1. put the test under an external directory that is added to the path, not
inside another package
2. patch the library by either
a) using relative imports (breaks compatibility with 2.4 and possibly 2.5
b) refactor using a library like py-ioc (http://code.google.com/p/py-ioc/),
a library that I wrote to solve similar problems
