Why this is showing error?

Why task 3 is showing error?

trial.py 
def add(n1,n2):
    try:
        add=float(input("Enter number"))
    except ValueError:
        print("Thats not a  number")
        return None
    else:

I think you've misunderstood the question. You are not supposed to request input from the user. The input to the function will be n1 and n2. You should try to convert n1 and n2 to float, and if successful, return the converted n1+n2. If you encounter a ValueError, return None instead.
