On a mac in python 2.7 when walking through directories using os.walk my script goes through 'apps' i.e. appname.app, since those are really just directories of themselves. Well later on in processing I am hitting errors when going through them. I don't want to go through them anyways so for my purposes it would be best just to ignore those types of 'directories'.

So this is my current solution:

for root, subdirs, files in os.walk(directory, True):
    for subdir in subdirs:
        if '.' in subdir:
            subdirs.remove(subdir)
    #do more stuff

As you can see, the second for loop will run for every iteration of subdirs, which is unnecessary since the first pass removes everything I want to remove anyways.

There must be a more efficient way to do this. Any ideas?

python python-2.7 os.walk
