Discarding STDERR generated during subprocess.popen

[Leon Derczynski]

Hi,

I would like to run an external program, and discard anything written
to stderr during its execution, capturing only stdout. My code
currently looks like:

def blaheta_tag(filename):
        blaheta_dir = '/home/leon/signal_annotation/parsers/blaheta/'
        process = subprocess.Popen([blaheta_dir + 'exec/funcTag',
blaheta_dir + 'data/', filename], cwd=blaheta_dir,
stdout=subprocess.PIPE)
        process.wait()
        return process.communicate()[0]

This returns stdout, and stderr ends up printing to the console. How
can I disregard anything sent to stderr such that it doesn't appear on
the console?

Thanks
