Optimizing tips for os.listdir

[Jaco Smuts]

I have not tested the speed on this, but I use the os.walk module for 
similair functionality.

I'm doing this :

[os.path.join(path, p) for p in os.listdir(path) if \
os.path.isdir(os.path.join(path, p))]

to get a list of folders in a given directory, skipping all plain
files. When used on folders with lots of files,  it takes rather long
time to finish. Just doing  a listdir, filtering out all plain files
and a couple of joins, I didn't think this would take so long. 

Is there a faster way of doing stuff like this?

Best regards,
Thomas
