Looking at some of
pysome's previous posts I'm guessing English is
not his first language. That may be one reason why he limits what he asks in posts. In fact, it's probably less confusing for us if he does that. I think it's important that we keep in mind that we have people from other parts of the world and people from other professions. Certainly the question could have been presented better but that may be too much to ask of
pysome. So kudos to you for finding it interesting enough to answer it!
