2.9. Exercise: Office Olympics

It’s Office Olympics time! Jim is trying to find the medalists by finding the three people that have the highest scores. Can you help him find the three people who have the most wins?

Write a program that takes a list of 2-tuples which consists of a string and an integer representing the name of people and their score and prints a list of 3 strings which are the names of 3 winners. You can assume that there are always at least three contestants in the Olympics.

Sample I/O:

Input:
wins_list = [("jim", 11), ("pam", 9), ("dwight", 12), ("oscar", 2), ("micheal", 17), ("angela", 3), ("kevin", 1)]

Output:
["micheal", "dwight", "jim"]

Input:
B = [("jim", 1), ("pam", 4), ("jan", 10), ("creed", 7), ("micheal", 5), ("meredith", 2), ("phyllis", 28)]

Output:

["phyllis", "jan", "creed"]
