7    :synopsis: Standard exception classes.
20 clause that mentions a particular class, that clause also handles any exception
21 classes derived from that class (but not exception classes from which *it* is
22 derived).  Two exception classes that are not related via subclassing are never

34 exception instance's :attr:`args` attribute.
36 User code can raise built-in exceptions.  This can be used to test an exception
