Using .map() with a dictionary

The .map() method is used to transform values according to a Python dictionary look-up. In this exercise you'll practice this method while returning to working with the election DataFrame, which has been pre-loaded for you.

Your job is to use a dictionary to map the values 'Obama' and 'Romney' in the 'winner' column to the values 'blue' and 'red', and assign the output to the new column 'color'.
