Copy directory tree without copying files

[Jeremy Conlin]

I am trying to copy a folder hierarchy from one location to another.
I can use the shutil.copytree function to copy the folder tree, but I
don't want the files copied, just the folders.  What is a good way to
approach this?

Thanks,
Jeremy

I was hoping to use os.walk, but this doesn't work because I wont know
when os.walk descends into a new directory or which directory it
descends into.  Perhaps I don't understand everything about it.

Thanks,

Thanks, that helps.  I could write a function like

def ignore_files(dirpath):
ignore = []
for f in os.listdir(dirpath)
if os.path.isfile(f):
ignore.append(f)
return ignore


That seems like it will work (haven't tested yet).  Thanks for the
help.

Perfect.  That's exactly what I needed.

Thanks, but this has to be platform independent so Python seemed like
a good choice.
