 Exception classes can be defined which do anything any other class can do, but
 are usually kept simple, often only offering a number of attributes that allow
-information about the error to be extracted by handlers for the exception.  When
-creating a module that can raise several distinct errors, a common practice is
-to create a base class for exceptions defined by that module, and subclass that
-to create specific exception classes for different error conditions::
-
-   class Error(Exception):
-       """Base class for exceptions in this module."""
-       pass
-
-   class InputError(Error):
-       """Exception raised for errors in the input.

-           expression -- input expression in which the error occurred
-           message -- explanation of the error

 Most exceptions are defined with names that end in "Error", similar to the
 naming of the standard exceptions.
