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