NEWBIE TIP: Displaying the contents of an imported module...from ENGSOL

[fleet at teachout.org]

I think I'm hung up on the substitution thing again.  If I wanted to name this 'show.py' and
be able to use 'python show.py math' on the command line - how do I get "import sys.argv[1]"
to work.  (and I would already have imported 'sys.')  I tried 'eval()' without success - kept
getting "invalid syntax" although the proper string was shown.
