Using the subprocess-module.
However, I'm not sure what DIR /AD /B does - but there are many
functions in module os that might deliver what you want without invoking
an external command.

Hey,
I did write the following:
but it does not work.
import subprocess as sp
try:
= sp.Popen("DIR . /AD /B", stdout=sp.PIPE)
result = p.communicate()[0]
print result
except:
print "error"
This throws error.
DIR . /AD /B will list out only directories in the current directory.
Thanks,
Indu

is a really bad idea because it hides any meaningful and therefore valuable
information about the error.
IIRC the "dir" command is internal to the dos shell and therefore has to be
called indirectly. The actual command is "cmd", not "dir":
[following snippet found at http://www.python-forum.de/viewtopic...f75c32cf67856]
>>import subprocess
args = ["cmd", "/C", "dir", "J:\\", "/O", "/AD", "/B"]
process = subprocess.Pope n(args, stdout = subprocess.PIPE , stderr =
subprocess.STDO UT)
>>print process.stdout. read()
If you just want a list of subdirectories, here's a better approach:
>>def directories(fol der):
.... return os.walk(folder) .next()[1]
>>directories(" .")
[snip list of subdirectories of cwd]

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
