Recommendation: If you don't understand something, keep it there :)
You can just copy and paste from the Python interactive interpreter
(command line or IDLE) straight into the email; it'll be easier to
explain, that way.

This is *especially* true of tracebacks. You might not see the
difference, but to us, it's often hugely helpful to see the entire
exception report.
