(Sum the digits in an integer) Write a function that computes the sum of the digits in an integer. Use the followving function header *6.2 def sumDigits(n): For example, sunDigits (234) returns 9 (2 + 3 + 4). (Hint: Use the % operator to extract digits, and the//operator to remove the extracted digit. For instance, to extract 4 from 234, use 234 % 10 (-: 4). To remove 4 from 234, use 234 // 10 23). Use a loop to repeatedly extract and remove the digits until all the digits are extracted.) Write a test program that prompts the user to enter an integer and displays the sum of all its digits
