If you are running the script under Python 2 you should use
raw_input() instead of input(). input() will take the user input and also
run eval() on it:
Python 2.7.6 (default, Mar 22 2014, 22:59:56)
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> input("? ")
? 1 + 1
2
>>> raw_input("? ")
? 1 + 1
'1 + 1'
Python 3 has no raw_input() and input() will behave like raw_input() in
Python 2.

In Python 2 capital.keys() builds a list. You can avoid that by iterating
over the dict directly:
for k in capitals:
...
Not an optimization, but if the user enters neither Y nor N you might ask
again instead of assuming Y.
