Convenience package offering

Project Description

This package allows you to do the fantastic import:

>>> from nihilo import nihil

This is a nice object which behaves like None but does accept method calls. Why would you want this?

So, we have:

>>> a_dict = { 'who': 'Parmenides' }
>>> print a_dict.get('who')
Parmenides
>>> print a_dict.get('where')
None
But you might want to do:
>>> a_dict.get('who').startswith('g')
False
>>> a_dict.get('where').startswith('g')
Traceback (most recent call last):
...
AttributeError: 'NoneType' object has no attribute 'startswith'
With nihil, you can do:
>>> print a_dict.get('where', nihil).startswith('g')
nihil()

Note that casting to bool returns false, so you can easily test..:

>>> if a_dict.get('where', nihil).startwith('g'):
...   print "got it!"

nihil is very flexible, it will also allow you to call almost any method and it will return itself:

>>> nihil.foo.bar('quux', frop=True)
nihil()

And remember, ex nihilo nihil fit.
