libb.emptydict

class emptydict

Bases: attrdict

A dictionary that returns None for non-existing keys without raising exceptions.

Similar to attrdict but returns None instead of raising KeyError or AttributeError when accessing non-existing keys.

Basic Usage:

>>> a = emptydict(a=1, b=2)
>>> a.c == None
True
>>> a.b
2
>>> a['b']
2
>>> 'c' in a
False
>>> 'b' in a
True
>>> a.get('b')
2
>>> a.get('c')
