change key in OrderedDict without losing order

Question

Starting with

OrderedDict([(\'a\', 1), (\'c\', 3), (\'b\', 2)])

is it possible to end up with

OrderedDict([(\'a\', 1), (\'_         


        

Answer 1

You could try:

>>> d = OrderedDict([('a', 1), ('c', 3), ('b', 2)])
>>> d
OrderedDict([('a', 1), ('c', 3), ('b', 2)])
>>> d2 = OrderedDict([('__C__', v) if k == 'c' else (k, v) for k, v in d.items()])
>>> d2
OrderedDict([('a', 1), ('__C__', 3), ('b', 2)])
