Python | Sum of number digits in List

When it is required to sum the number of digits in a list, a simple loop and the ‘str’ method can be used.

A list can be used to store heterogeneous values (i.e data of any data type like integer, floating point, strings, and so on).

The ‘str’ method converts the given value into a string data type.

Below is a demonstration for the same −

Example

 Live Demo

my_list = [11, 23, 41, 62, 89, 0, 10] print("The list is : ") print(my_list) my_result = [] for elem in my_list:    sum_val = 0    for digit in str(elem):       sum_val += int(digit)    my_result.append(sum_val) print ("The result after adding the digits is : " ) print(my_result)

Output

The list is : [11, 23, 41, 62, 89, 0, 10] The result after adding the digits is : [2, 5, 5, 8, 17, 0, 1]

Explanation

• A list is defined, and is displayed on the console.
• Another empty list is created.
• The list is iterated over, and every element in the list is converted to a string, and iterated over.
• It is then added and converted as a single digit.
• This is done on all elements of the list.
• This is appended to the empty list.
• It is then displayed as output on the console.
