I would write it as
- or certainly split it into two lines, because the current directory may
not be the directory containing the script.

Note that this only applies to *packages*, not alone modules. And if you
already have a package, it's better to put the driver/test/demo code out
of the package itself, this way it must import the package the same way as
any other client code. I usually place them in the directory containing
the package (so "import package" just works). Other people prefer a
different layout; search for some recent posts on this subject.
