Greetings all.
I did some searching on this but I can't seem to find a specific
solution. I have code like this:
=========================================
def walker1(arg, dirname, names):
DC_List.append((dirname,''))
os.path.walk('\\\\vcdcflx006\\Flex\\Sites', walker1, 0)
=========================================
The Sites\ directory is set up like this:
Sites\
Baltimore
Birmingham
....
And so forth. Each of the city directories has directories under it as
well. The problem is that my code grabs every single directory that is
under the various city directories when what I really want it to do is
just grab the directories that are under Sites\ and that's it. I don't
want it to recurse down into the sub-directories of the cities.
Is there a way to do this? Or is os.path.walk not by best choice here?
Yes. But first, use the more modern iterator os.walk instead of the
older function calling os.path.walk. Then in either case (or at least
for the os.walk -- I'm a little rusty on the older os.path.walk) you can
modify in-place the subdirectory listing that was passed to you, thereby
controlling which subdirectories the walk follows.
Here's some examples:
for path, dirs, files in os.walk(root):
if 'etc' in dirs:
dirs.remove('etc') # Skip any directory named 'etc'
if path == 'whatever':
del dirs[:] # Clearing dirs means recurse into NO
subdirectory of path
... process the files of directory path...

Any help and/or advice would be appreciated.
