grab dict keys/values without iterating ?!

You were absolutely right.
I don't want to iterate the entire dict to get me the key/values
Let us say this dict would have 20.000 entries, but I want only those
with "Aa" to be grabed.
Those starting with these 2 letters would be only 5 or 6 then it would
take a lot of time.
In which way would you prefer to store the data, and which functions or
methods would you use effectively to accomplish this task ?
I deeply apologize of not defining the question more defined. English is
not my mother tongue.
I'll do my best next time.
