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.
