HackerRank - Python Introduction to Sets


Let's use our knowledge of sets and help Mickey.

Ms. Gabriel Williams is a botany professor at District College. One day, she asked her student Mickey to compute the average of all the plants with distinct heights in her greenhouse.



  1. def average(heights):

  2.     heights = set(heights)

  3.     return sum(heights) / len(heights)

  4. 

  5. if __name__ == '__main__':

  6.     n = int(input())

  7.     arr = list(map(int, input().split()))

  8.     result = average(arr)

  9.     print(result)
