I will point you toward two things. First, the dict class has a method
called values(). Read the documentation on that, go into your
interpreter, make some dictionaries, and call the values() method, see
what comes up.
The second thing is the sum() method. Again, read the documentation on
it and experiment with it a little. Those two should suffice to answer
your question.
I always encourage people to play around with their problems in the
interactive interpreter, discovering what works and what doesn't for
yourself is often a great way to learn. Combine that with
http://docs.python.org and you've got some very powerful learning
tools
