Bunch is a dictionary that supports attribute-style access, a la JavaScript.

>>> b = Bunch()
>>> b.hello = 'world'
>>> b.hello
'world'
>>> b['hello'] += "!"
>>> b.hello
'world!'
>>> b.foo = Bunch(lol=True)
>>> b.foo.lol
True
>>> b.foo is b['foo']
True

A Bunch is a subclass of dict; it supports all the methods a dict does:

>>> b.keys()
['foo', 'hello']

Including update():

>>> b.update({ 'ponies': 'are pretty!' }, hello=42)
>>> print repr(b)
Bunch(foo=Bunch(lol=True), hello=42, ponies='are pretty!')

As well as iteration:

>>> [ (k,b[k]) for k in b ]
[('ponies', 'are pretty!'), ('foo', Bunch(lol=True)), ('hello', 42)]

And "splats":

>>> "The {knights} who say {ni}!".format(**Bunch(knights='lolcats', ni='can haz'))
'The lolcats who say can haz!'

• Bunch converts easily to (unbunchify, Bunch.toDict) and from (bunchify, Bunch.fromDict) a normal dict, making it easy to cleanly serialize them to JSON or YAML. (In fact, Bunch attempts to register itself with `PyYAML<http://pyyaml.org/wiki/PyYAML>`_ so that Bunches can be transparently dumped and loaded.)

• It is safe to import * from this module. You'll get: Bunch, bunchify, and unbunchify.

• Tests:

  $ python -m bunch.test -v
