Python: Compute the sum of digits of each number of a given list of positive integers

Python Itertools: Exercise-34 with Solution

Write a Python program to compute the sum of digits of each number of a given list of positive integers.

Sample Solution:

Python Code:

from itertools import chain
def sum_of_digits(nums):
    return sum(int(y) for y in (chain(*[str(x) for x in nums])))

nums = [10,2,56]
print("Original tuple: ") 
print(nums)
print("Sum of digits of each number of the said list of integers:")
print(sum_of_digits(nums))

nums = [10,20,4,5,70]
print("\nOriginal tuple: ") 
print(nums)
print("Sum of digits of each number of the said list of integers:")
print(sum_of_digits(nums))

Sample Output:

Original tuple: 
[10, 2, 56]
Sum of digits of each number of the said list of integers:
14

Original tuple: 
[10, 20, 4, 5, 70]
Sum of digits of each number of the said list of integers:
19
