Oh, Dale, you've given me a feeling of deja vu!
For starters, you might want to review this thread
where I asked nearly the same questions.
Also, a list of all python exceptions can be found in the documentation.
Look in the Library Reference, under built-ins. You will find exceptions
I recently had an small epiphany, where I found a case where I wrote an
exception that required an init, and thought it was a better example (at
least to me) than any I'd seen so far as to why I might want my own init
routine on an exception class. I can't recall it right now. (Was going
to eventually write it up, but didn't do it right then, and it's been a
few weeks now.) Maybe late tomorrow I will have time to go digging for
that and post it as an example.
