Hi,
I've been reading up on list comprehensions lately, all userful and powerful
stuff - trying to wrap my brain around it :)
As the examples all seem to relate to lists, I was wondering if there is an
elegant similar way to apply a function to all keys in a dictionary?
(without looping over it, of course)
I'm trying to convert all keys in a dict to uppercase, as in:
INPUT:
age_dict = { 'pete': 42, 'ann': 25, 'carl': 30, 'amanda': 64 }
OUTPUT:
age_dict = { 'PETE': 42, 'ANN': 25, 'CARL': 30, 'AMANDA': 64 }
I googled 'dictionary comprehension' but couldn't get any code to work with the
examples given.

thanks,
Pete
