Task 3 Help

I don't understand the last bit with the return and added floats, I don't know what to do

trial.py 
def add(num1, num2):
try:
    return float(num1) + float(num2)
except ValueError:
    return None
else:
    return

You have almost everything!

def add(arg1, arg2):
    try:
        return float(arg1) + float(arg2)
    except ValueError:
        return None
    else:
        return arg1 + arg2

You are just missing the return num1 and num2 on your else return on the end! but you got this!

Hey John Paul,

You code is actually completely correct except for the indentations. Python is very "indent dependent," and if your off by one space, the code will break.

In this case, you didn't indent your try block of code, so right now, it is outside of the method, instead of inside. Just fix up the indentation and the rest is good:

def add(num1, num2):
    try:
        return float(num1) + float(num2)
    except ValueError:
        return None
    else:
        return

Keep Coding! :) :dizzy:
