Another approach is to always print a friendly error message,
but append the traceback to a log file (see the traceback
module for how to do that.) The friendly error message can
include a note that full information is available in the log
file.
The advantage of that is that you capture critical information
that is otherwise lost when a non-expert user hits the exception.
For intermittent bugs that are hard to reproduce, this can be
a lifesaver - especially when your favorite non-expert user
seems to have a knack for generating errors that you can't figure
out how to create ;-)
