Sure, but I'm keeping this on list.

os.path.split basically does the same thing you do.

# maintaining your non-PEP-8 names
rootPath = os.path.abspath(__file__)
rootPath = os.path.split(os.path.split(rootPath)[0])[0]

os.path.join simply joins pieces together, so you could join a couple
of ".." to your path.

rootPath = os.path.abspath(os.path.join(__file__, "..", ".."))

Advantage: They don't depend on backslashes in file paths, so they'll
work on all platforms.
