I\'m developing a Python application; it has all its code in one package and runs inside this of course. The application\'s Python package is of no interest from the interpr

The Python Style Guide recommends explicitly against relative imports (the . style):

Relative imports for intra-package imports are highly discouraged. Always use the absolute package path for all imports. Even now that PEP 328 [7] is fully implemented in Python 2.5, its style of explicit relative imports is actively discouraged; absolute imports are more portable and usually more readable.

I tend to agree. Relative imports mean the same module is imported in different ways in different files, and requires that I remember what I'm looking at when reading and writing. Not really worth it, and a rename can be done with sed.

Besides the issue of renaming, the only problem with absolute imports is that import foo might mean the top-level module foo or a submodule foo beneath the current module. If this is a problem, you can use from __future__ import absolute_import; this is standard in Python 3.
