You're doing great! Just one more task but it's a bigger one. Right now, we turn everything into a float. That's great

i am lost and i dont know where

trial.py 
def add(num1, num2):
    try:
        return int (num1) + int (num2)
    except ValueError:
        return None
    else:
        return num1 + num2
        a = float(num1)
        b = float(num2)
        return a + b

Hi there!

Ah so close! The good news is you get the try,except,else block, I think maybe the question just threw you a bit.

Your try case will return the numbers as integers if they can be converted to ints. It actually wants you to return floats like in the last question, so rather than return in your try condition, just reassign the variables to floats, and then you can return them, added together in the else case.

Hope it helps!

Hello, I am also seem to be having trouble with the third task in this quiz, right now I have:

def add(bob, sue):
        try:
            return int(bob) + int(sue)
        except ValueError:
            return None
        else:
            return(float(bob) + float(sue))

What am I doing wrong or missing?

Please & Thank you for any help
