So suppose I want to modify the sys.path on the fly before running some code

at run time I do
sys.path.extend(paths_to_add)

Make sure you are adding to sys.path the directories that your
packages/modules are in, and not the actual package directories.
During import Python looks for modules/packages _in_ each of the
directories on sys.path, but not _at_ those directories.
Yes sure I do this..
If I take these paths and add them to site-packages/my_paths.pth
everything works, but at run-time the paths which I actually see before
importing are exactly the same.
You mean sys.path looks exactly the same in the two cases?

Yes they are exactly the same, because in that file I just write exactly
the same list,
but when modifying it at run-time it doesn't work, while if at the
application start
there is this file everything works correctly...
That's what really puzzles me.. What could that be then?
