Lastest release
version 0.6.1 on Sep 20th, 2013

Implements the null object pattern.

Provides:

  • a Null singleton that can be used like None (but is not None and is not equal to None)
  • a NullList that returns Null instead of raising IndexError
  • a NullDict that returns Null instead of raising KeyError
  • a nullify() routine that converts mappings and sequences to the nullified variant
  • an unset singleton for clearing up APIs to distinguish between a keyword argument that is set by the user as None and simply not set by the user

How do I run the tests?

The easiest way would be to extract the source tarball and run:

$ python test/test_null.py
