subprocess.Popen - file like object from stdout=PIPE

using e.g.
import subprocess
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

for line in EQ_OUT :

I could use StringIO.StringIO applied to EQ_output
but this reads all of the command's output into a big
string first.

On Unix/Linux a pipe is a file-like object after all,
so how to get hold of it.

Many thanks for a hint,
