I hope it's not - or I'll be quite annoyed :)

Hi,
There is "never" a "clever" way
of doing anything, but:
$ cat test.py
MAPPING_DICT = {'a': 'A','b': 'B',}
my_dict = {'a': '1','b': '2'}
my_dict = dict((MAPPING_DICT[k], my_dict[k]) for k in my_dict)
print my_dict
$ python test.py
{'A': '1', 'B': '2'}
$
That should do the trick.
cheers

since none of your dictionaries contain the keys you want in the final
dictionary, creating a brand new dict sounds pretty clever to me.
