Hi Alan,
Thanks for your reply.
My answer to why I am using os.popen could be a lame one - I have used it
extensively in various places before and it has been working well and so
was hung up on using it. Now I replaced it by subprocess.check_output with
appropriate parameters and it seems to be wor

This doesn't answer the question but I'm curious.
If you read about os.popen in the subprocess module docs why did
you use it? The subprocess module replaces all the os.popen

Hello,
I am using os.popen repeatedly to run Unix shell commands within my Python

It works fine

Well, as usual thanks for all this, it's really great. I'd worked out
that it was a distinction between iterators and iterables, though I'm
going to Oscar's description a few more times: most of it made sense,
but there are subtleties.
