Python: Compute the average of nth elements in a given list of lists with different lengths
Python List: Exercise - 197 with Solution
Write a Python program to compute the average of the n-th element in a given list of lists with different lengths.
Sample Solution:
Python Code:
import itertools as it
nums = [[0, 1, 2],
[2, 3, 4],
[3, 4, 5, 6],
[7, 8, 9, 10, 11],
[12, 13, 14]]
print("Original list:")
print(nums)
def get_avg(x):
x = [i for i in x if i is not None]
return sum(x, 0.0) / len(x)
result = map(get_avg, it.zip_longest(*nums))
print("\nAverage of n-th elements in the said list of lists with different lengths:")
print(list(result))
Sample Output:
Original list: [[0, 1, 2], [2, 3, 4], [3, 4, 5, 6], [7, 8, 9, 10, 11], [12, 13, 14]] Average of n-th elements in the said list of lists with different lengths: [4.8, 5.8, 6.8, 8.0, 11.0]
