Andy McDonald
Python Development Techdegree Graduate 13,801 PointsCalling the function within the function
This part is really hard for me to conceptualize, to run the function again an return new values. I figure I have to call it based upon the values I got on the first time around but I'm not sure how to turn the function on those items within the items in the dict. I just really don't know the syntax for doing that.
