Where's the standard python exception list for programmes to raise?

Question

There is a list standard python exceptions that we should watch out, but I don't think these are the ones we should raise ourselves, cause they are rarely applicable.

I'm curious if there exists a list within standard python library, with exceptions similar to .NET's ApplicationException, ArgumentNullException, ArgumentOutOfRangeException, InvalidOperationException — exceptions that we can raise ourselves?

Or is there different, more pythonic way to handle common error cases, than raising standard exceptions?

EDIT: I'm not asking on how to handle exceptions but what types I can and should raise where needed.

Answer 1

If the error matches the description of one of the standard python exception classes, then by all means throw it.

Common ones to use are TypeError and ValueError, the list you linked to already is the standard list.

If you want to have application specific ones, then subclassing Exception or one of it's descendants is the way to go.

To reference the examples you gave from .NET ApplicationException is closest to RuntimeError ArgumentNullException will probably be an AttributeError (try and call the method you want, let python raise the exception a la duck typing) AttributeOutOfRange is just a more specific ValueError InvalidOperationException could be any number of roughly equivalent exceptions form the python standard lib.

Basically, pick one that reflects whatever error it is you're raising based on the descriptions from the http://docs.python.org/library/exceptions.html page.
