Complete a recursive function, called sumDigits, in the incomplete Python program given below. This recursive function should compute and return the sum of all the digits in the would generate the following output: Enter a multi-digit number: 6347 positive integer to be passed to the function. For example, given 6347 as input, the program The sum of the digits is 20 Here is the incomplete program def def main(): number int (input("Enter a multi-digit number: ")) print("The sum of the digits is", sumDigits(number)) main()
