I am not sure where to insert the try keyword here, need help

def add(x,y):
        sum = (float(x) + float(y))
    except ValueError:
        return None
    return (float(x) + float(y))

type checking. If x or y was a string or array, it couldn't be converted into a float therefore it needs to be handled. Extra... why calculate the sum again when it you've already stored the value?
