Another place :keyword:`pass` can be used is as a place-holder for a function or
-conditional body when you are working on new code, allowing you to keep

-ignored, a better choice may be to raise a :exc:`NotImplementedError`

+conditional body when you are working on new code, allowing you to keep thinking
+at a more abstract level. The :keyword:`pass` is silently ignored::
>>> def initlog(*args):
- ... raise NotImplementedError # Open logfile if not already open
- ... if not logfp:
- ... raise NotImplementedError # Set up dummy log back-end
- ... raise NotImplementedError('Call log initialization handler')
+ ... pass # Remember to implement this!
...
-If :keyword:`pass` were used here and you later ran tests, they may fail
-without indicating why. Using :exc:`NotImplementedError` causes this code
-to raise an exception, telling you exactly where the incomplete code
-is. Note the two calling styles of the exceptions above.
-The first style, with no message but with an accompanying comment,
-lets you easily leave the comment when you remove the exception,
-which ideally would be a good description for
-the block of code the exception is a placeholder for. However, the
-third example, providing a message for the exception, will produce
-a more useful traceback.
