Re: Gettings subdirectories

[Philippe Martin]

Hi,

The second edition of Programming Python - O'REILLY - Mark Lutz shows how
to do that using os.path.walk

If you're not adverse to a solution outside of the standard lib, I
highly recommend the 'path' module:

 from path import path
 c = path(C:\\)
 c.dirs()
[path(u'C:\\cmdcons'), path(u'C:\\Config.Msi'), path(u'C:\\Logon'),
path(u'C:\\Program Files'), path(u'C:\\Python24'),
path(u'C:\\RECYCLER'), path(u'C:\\System Volume Information'),
path(u'C:\\WINDOWS'), path(u'C:\\WINSRC')]

Hope this helps.

Gettings subdirectories

 os.listdir() gives me all entries and I've found no way to tell if
 an object is a file or a directory.

Why, doesn't your os.path.isdir() function work?

It's a bit overkill, but consider using os.walk.

root, dirnames, filenames = os.walk(rC:\).next()  # (in real code,
you'd want to catch exceptions here)
print dirnames

 root, dirnames, filenames = os.walk(rC:\).next()

Wow. How does that work? Just point me to where I can read about it. I
don't see it under os.walk.

That's cool.

Thanks,

We must be reading different Python websites.

walk(top[, topdown=True  [, onerror=None]])

walk() generates the file names in a directory tree, by walking
the tree either top down or bottom up. For each directory in the
tree rooted at directory top (including top itself), it yields a
3-tuple (dirpath, dirnames, filenames).

Maybe he meant os.path.walk, although that's still not quite what he had.

Re: Gettings subdirectories

[BartlebyScrivener]

Sorry that I was unclear.

I sorta know how os.walk works. It's the .next() trick that I had never
seen before. For instance, if you run that statement without the
.next() on it, it says Too many items to unpack but with the .next()
it stops it somehow, right where I want it to stop.

It's an iterator method, right? I found it in Beazely, now I'll try to
understand it. Sorry to trouble you.

Here is a quick hack:

import os
import os.path

givenDir = /
listing = os.listdir(givenDir)
for item in listing:
 joinPath = os.path.join(givenDir, item)
 normPath = os.path.normpath(joinPath)
 if os.path.isdir(normPath):
 print normPath
