Python Python Basics (2015) Logic in Python Try and Except

Functions: Float, Try, Except and Else

I followed step by step to my abilities, I think there should something else after the try block but I'm not certain what I'm doing wrong!

trial.py
def add(whats, up): 
    try:
    except ValueError
        return None
    else:
        return float(whats) + float(up)

Hi Noel,

You're very close. The only thing that you have to change is the order of things. As written, your code asks to try something, but then doesn't state what to try. You can change your code to try to return float(whats) + float(up) and if it fails, return None. Since you are converting your variables and returning the value at the same time, there isn't really a need for an else, as your try statement already performs all the functionality required in the challenge.

Take a look and good luck!

Thanks Elad, i guess I misread the question and thought i needed an else
