Question

How to sort this dictionary by 'votes' in Python?

{
  1 : {
    'votes' : 2,
    'id' : 10
  },
  2 : {
    'votes' : 10,
    'id' : 12
  },
  3 : {
    'votes' : 98,
    'id' : 14
  }
}

To results in:

{
  3 : {
    'votes' : 98,
    'id' : 14
  },
  2 : {
    'votes' : 10,
    'id' : 12
  },
  1 : {
    'votes' : 2,
    'id' : 10
  }
}

You could use an OrderedDict:

>>> from collections import OrderedDict
>>> od = OrderedDict(sorted(d.items(),
                     key=lambda t: t[1]['votes'],
                     reverse=True))
>>> od
OrderedDict([(3, {'votes': 98, 'id': 14}),
             (2, {'votes': 10, 'id': 12}),
             (1, {'votes': 2, 'id': 10})])

where d is your original dictionary.
