[Tutor] subprocess.Popen(..., cwd) and UNC paths

[Albert-Jan Roskam]

Hello,

Windows has the 'feature' that the CD command does not work with UNC paths.
So in the code below, I cannot use the 'cwd' parameter of subprocess.Popen.
Therefore I use pushd/popd to accomplish the same effect. Is there a better way to do this?
(other than using full path names everywhere, or os.chdir). Would it be a useful improvement
of Python itself if cwd also works with UNC path? 

import sys
import os
import getpass
import subprocess

path = r'\\server\share\possibly with\space'
executable = 'blah.exe'
username = os.getenv("USERNAME")
password = getpass.getpass("Enter password: ")
infile =  sys.argv[1]
outfile = sys.argv[2]
cmds = ['pushd "%s" &&' % path, executable, username, password, infile, outfile, "&& popd"]

result = subprocess.Popen(" ".join(cmds), shell=True)
error = result.stderr
if error:
    raise RuntimeError(error.read())

Regards,

Albert-Jan
