Not sure why this isn't working? I think I have all the try, except, and else commands in the right place

Could anyone solve this?

trial.py 
def add(a, b):
    try:
        float(a) + float(b)
    except ValueError:
        return None
    else:
        print(a+b)
add(1,3)

You are very close! Currently, you code does nothing with the results of the float(a) + float(b) statement. If no result happens due to an error, the except code will return a value. But what if the float addition is successful? Instead of falling through to the else code, you could simply return the result of the float addition by put a return in front off it.

The else code, as well as the call to add(1, 3), is not needed.

Post back if you need more help. Good luck!!
