Question

I need answer of this question: Write a program that reads values from the user until a blank line is entered. Display the total of all of the values entered by the user (or 0.0 if the first value entered is a blank line). Complete this task using recursion. Your program may not use any loops. in python programming lenguage

Answer 1

Program:

def fun():

   n = input("If you want to exit enter a blank line otherwise enter a value : ")

   if n == "":

       return 0.0

   else:

       n = int(n)

       return (n + fun())

print("Total of all the values = ", fun())

Output 1:

If you want to exit enter a blank line otherwise enter a value : 1

If you want to exit enter a blank line otherwise enter a value : 2

If you want to exit enter a blank line otherwise enter a value : 3

If you want to exit enter a blank line otherwise enter a value : 4

If you want to exit enter a blank line otherwise enter a value :

Total of all the values = 10.0

Output 2:

If you want to exit enter a blank line otherwise enter a value :

Total of all the values = 0.0
