This is what it's asking.
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.
try: def add(num1,num2): num1 = float(num1) num2 = float(num2) return(num1 + num2) except ValueError: return(none) else: print(num1) print(num2)

You are headed in the right direction.
trystatement should be inside the function definition and all the subsequent statements properly indented.
- The return value in the
exceptblock should be
exceptwill result in a
- The return statement isn't a function, so parentheses should not be used.
Post back if you need more help. Good luck!!
