You do not want to use types as exceptions, you want to use either
strings or exceptions.

: try:
:     ... code raising exception
: except EOFException, err:
:     pass

: Only strings and python classes seem to be allowed.

And C exception classes created with PyErr_NewException().  This
creates a subclass of "Exception" which can be used to raise and catch
exceptions.

You might want to read:
http://www.python.org/doc/current/api/exceptionHandling.html and
http://starship.python.net/crew/arcege/extwriting/pyext.html (under the
section "Making an exception").
