For cmd line, yes that's basically it. When I say "shell", I'm referring
to the Python IDLE GUI.

That's correct, I did have two versions installed. I first installed ver
2.7, then later installed ver 3.4 when I began going through the lessons in
the aforementioned book. Although I'd taken steps to ensure the latest
version was used, I was apparently not thorough enough as when I inserted
some code in the program that revealed the version being used, it stated
2.7.4. So, I ended up uninstalling both versions, then reinstalling ver
3.4 which reset the file associations and resolved the issue.
Hopefully any further issues I encounter aren't due to misconfigurations
and the like.
Thanks for your help, Steven.
