I need to run a command using subprocess.Popen() and have stdin

self.process = subprocess.Popen(argv,

stdout=open(outfile, 'w'),
stderr=open(errfile, 'w'),
stdin=open('/dev/null')
)
but that's not portable to windows. Does Python have a portable way
to get a file object connected to the null device, regardless of what
operating system you're running on?
I normally just implement my own object:
class DevNull:
def write(self, str):
pass
I bet this won't work. It needs to be a "real" file - have a file
descriptor or a handle or something.
Instead, try opening os.devnull.
