def points(): | |
''' | |
Imagine a point system in which each country is awarded 4 points for each | |
gold medal, 2 points for each silver medal, and one point for each | |
bronze medal. | |
Using the numpy.dot function, create a new dataframe called | |
'olympic_points_df' that includes: | |
a) a column called 'country_name' with the country name | |
b) a column called 'points' with the total number of points the country | |
earned at the Sochi olympics. | |
You do not need to call the function in your code when running it in the | |
browser - the grader will do that automatically when you submit or test it. | |
