Implements the null object pattern.
Project description
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
