except ValueError

Here is the challenge: 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 so long as we're getting numbers or numbers as a string. We should handle cases where we get a non-number, though. Add a try block before where you turn your arguments into floats. Then add an except to catch the possible ValueError. Inside the except block, return None. If you're following the structure from the videos, add an else: for your final return of the added floats. My answer fails; but I can't tell what I am doing wrong. My original syntax was this def add(num1, num2): return(float(num1) + float(num2))

def add(num1, num2):
try:
    return(float(num1) + float(num2))
except ValueError:
    return ("None")
else:
    return(float(num1) + float(num2))
