Or use itemgetter:

  >>> from operator import itemgetter
  >>> dct = {'greeting': 'hello', 'thing': 'world', 'farewell': 'bye'}
  >>> thing, greeting = itemgetter("thing", "greeting")(dct)
  >>> thing
  'world'
  >>> greeting
  'hello'

Ohhh, nice. Also, attrgetter (which also supports dotted notation to get nested attrs! Sadly, no dotted notation for itemgetter.)

    Dotted notation would not work because the keys in a dict can also contain dots. I am not terrible familiar with them but there is something called `lenses` that comes from functional programming that should allow you to access nested structures. And I am pretty sure there must be at least one python library that implements that.
