Hello,
how can I get all subdirectories of a given directory. os.listdir(dir)
doesn't differentiate between directories and files, os.walk seems to me a
bit overkill since it also descends in the subdirs.
Thx,

#!/usr/bin/env python
import os
dir = '.' # '.' is current directory
for i in os.listdir(dir) :
if os.path.isdir(o s.path.join(dir , i)):
print i
Bby the way, on Linux, I noticed that the directories '.' and
'..' are not returned by os.listdir

What about testing return values of os.listdir with os.path.isdir?
e.g.,
filter(os.path. isdir, os.listdir(dir) )
or if you don't like high-order functions,
[filename for filename in os.listdir(dir) if os.path.isdir(f ilename)]

I'm a fan of the path module:
from path import path
p = path("my_direct ory")
l = [i.name for i in p.dirs()]

[Florian Lindner] how can I get all subdirectories of a given directory. os.listdir(dir) doesn't differentiate between directories and files, os.walk seems to me a bit overkill since it also descends in the subdirs.
os.walk() is a generator -- it doesn't descend into anything unless
you resume it. That's the usual case, but you don't need to resume
it.
def subdirs(dir):
"Return list of the subdirectories of dir."
for root, dirs, files in os.walk(dir):
return dirs
works fine, or, perhaps more obscurely,
def subdirs(dir):
"Return list of the subdirectories of dir."
return os.walk(dir).ne xt()[1] This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

I have an existing code base that I want to import into VS 7.1 C++. It has
200+ include files in 20+ subdirs.
e.g.
incl/package/classfile.h
incl/package2/classfile2.h
I want to add all of these files recursively to the project. Is there a
known trick/utility to do this ?

Hello,
I was wondering how I can reference assemblies from web.config files
residing in subdirectories without having to create a new project for each
web.config-containing subdirectory?
I would like to use an HttpModule, but only for files in a particular
directory, so I add a web.config file containing this:

Hello,
I'm playing around with os.walk and I made up del_tree(path) which I
think is correct (in terms of the algorithm, but not as python wants
it :)).
As soon as some directory is deleted the iterator of os.walk chokes.
OK that is somehow clear to me as it can't be valid anymore since it
can't go to the just deleted directory but it is in the iterator.
