Question

5. Write a program that asks the user to input a set of floating-point values. When the user enters a value that is not a number, give the user a second chance to enter the value. After two chances, quit reading input. Add all correctly specified values and print the sum when the user is done entering data. Use exception handling to detect improper inputs.5 pts

   2. A screenshot of the execution

Test Case:

      Enter float: 1.0

      Enter float: 0.5

      Enter float: A

                  Error: that is not a number

      Enter float: B

                  Error: that is not a number

      The sum of the numbers is 1.5

Python, keep it simple, thank you

Answer 1

Python code:

#initializing total as 0
total=0
try:
    #looping till an invalid number is entered
    while(True):
        #accepting number
        num=float(input("Enter float: "))
        #adding it to total
        total+=num
except:
    #printing Error
    print("Error: that is not a number")
    try:
        #looping till an invalid number is entered
        while(True):
            #accepting number
            num=float(input("Enter float: "))
            #adding it to total
            total+=num
    except:
        #printing Error
        print("Error: that is not a number")
#printing total
print("The sum of the numbers is",total)
