using e.g.

EQ=subprocess.Popen(['/usr/bin/equery','depends',Package],stdout=subprocess.PIPE)
EQ_output= EQ.communicate()[0]
EQ_output is a string containing multiple lines.
I'd prefer a file-like object, e.g. EQ_OUT
so that I can loop over the lines of it like
EQ.stdout is the filelike object you're looking for.
communicate() grabs entire output at once so don't use it.
import subprocess
Package = 'app-arch/lzma-utils'
EQ = subprocess.Popen(['/usr/bin/equery', 'depends', Package],
stdout=subprocess.PIPE)
for line in EQ.stdout:
do_stuff_with(line)
Thanks a lot, I haven't found that in the official documentation.
Helmut.
