Implement a function inValues() that asks the user to input a set of nonzero floating-point values. When the user enters a value that is not a number, give the user a second chance to enter a value. After two mistakes in a row, quit the program. When the user enters 0, the function should return the sum of all correctly entered values. Use exception handling to detect improper inputs.

Explanation:

The following is written in Python and uses exception handling to do exactly as requested. It then goes adding all of the integer values to an array called num_list and finally adding them all together when the function ends.

def in_values():

   num_list = []

   while True:

       try:

           num = input("Input non-zero floating point: ")

           num = int(num)

           if num == 0:

               break

           else:

               num_list.append(num)

       except ValueError:

           print("No valid integer! Please try again ...")

           try:

               num = input("Input non-zero floating point: ")

               num = int(num)

               break

           except ValueError:

               break

   sum = 0

   for number in num_list:

       sum += number

   return sum
