Read the docs! (http://docs.python.org/library/os.html#os.walk):
They even include a specific code example of how to skip unwanted
subdirectories.
You will run into problems however if you want to delete from a tree
while ignoring certain named directories. Directories must be empty
before they can be deleted, so you must use "topdown=False", but to
prune a search you must use "topdown=True". At least I think that was
the problem I had with my deletion script a while back.
I'd say the problem is ill-defined in that case. You have to decide what
to do with those non-empty directories that are non-empty because you
explicitely skipped some subdirectories...
