Inherit from an existing exception.

.... pass
....Traceback (most recent call last):
File "<stdin>", line 1, in <module>
__main__.MyValueException: value is impossible, try again


.... pass
....Traceback (most recent call last):
File "<stdin>", line 1, in <module>
__main__.GenericError: oops


Do you need anything more complicated?

Traceback (most recent call last):


...     pass
...>>> raise GenericError("oops")

Traceback (most recent call last):
