Others has described how to do what you wanted to do, but let's address
the main problem here, why are you iterating a dictionary?
I found that most of the time that I thought I needed to iterate through
a dictionary, it's really because I'm thinking the wrong way, and a
little bit more thought lead me to a better way that doesn't involve
iterating on the dictionary.
While there are legitimate reasons for iterating a dictionary, I'd
consider the alternatives first.
