The use that first springs to my mind is debugging import paths etc.
If you have multiple pythons installed and aren't sure that they're
finding the right modules, you could fire up PyWhich on an innocuous
module like math or sys, and see if it's loading it from the right
path. People doing this might not necessarily be programmers, they
might be sysadmins; but you're right that it's most likely this will
be used by competent Python programmers.

I am trying to do debugging. I have had some trouble with multiple
python installs with virtualenv, and I was trying to see where given
modules came from. I knew about the code execution, but I couldn't
think of a clean way to just find out the location rather than load it.
The reason I used stdout was because I was going to be using it in a
tool chain where the stdout might need to be formatted for another
program to read in. Thats also why I was catching ImportError since a
later version of this script might need to do something special with it.
This is also useful to see if python is really using the module you
think it is.
