Ordered Dict, preserve initial Order

Question

Ordered Dict:

import collections
d = {\'banana\': 3, \'apple\':4, \'pear\': 1, \'orange\': 2}
collections.OrderedDict(sorted(d.items(), key=lamb         


        

Answer 1

Initial order is preserved for an OrderedDict, so just put it straight in and bypass the regular dictionary:

>>> from collections import OrderedDict
>>> od = OrderedDict([('banana', 3), ('apple', 4), ('pear', 1), ('orange', 2)])
>>> od
OrderedDict([('banana', 3), ('apple', 4), ('pear', 1), ('orange', 2)])
