[Tutor] How much in a "try" block?

[leam hall]

Well, maybe I'm looking at the wrong construct. The script needs to open up
one file that will be on the machine. It will open up other files given as
command line arguments and open files to write to. It should fail
gracefully if it cannot open the files to be read or written. The community
that will use the script has varying levels of scripting but not hordes of
Python. I'd prefer to fail with an explanation so they could fix the issue
and not just blame the script.
