Task 3 challenges

Question

I was able to get the desired result in workspaces, but when answering the third task for the question. Am I missing something here?
def add(num1, num2):
    try:
        num1 = int(input("Give me a number "))
        num2 = int(input("Give me another number "))
    except ValueError:
        return("None")
    else:
        return(float(num1) + float(num2))
answer = add(9,9)
print(answer)
```trial.py
def add(num1, num2):
    try:
        num1 = int(input("Give me a number "))
        num2 = int(input("Give me another number "))
    except ValueError:
        return("None")
    else:
        return(float(num1) + float(num2))
answer = add(9,9)
print(answer)
```

Hmm I think you have overcomplicated it, here you go:
def add(x,y):
    try:
        a = float(x)
        b = float(y)
    except ValueError:
        return None
    else:
        return a + b

Hi !
They wanted you to use the try/except blocks or the if/else blocks but not both at the same time, because as you can see there is no if in your code, then you can't just add a else, here is a simple solution to your problem :
python
def add(num1, num2):
    try:
        return float(num1) + float(num2)
    except ValueError:
        return None
