def add(num1, num2) : float(num1) float(num2) Result = num1 + num2 return(Result) add(1,2)

trial.py 
def add(num1, num2) :
    float(num1)
    float(num2)
    Result = num1 + num2

Calling "float" doesn't change the number it works on, it just returns the converted result. So doing it by itself isn't very useful.

But you could store the result back into the variable:

    num1 = float(num1)

Also, the challenge only asks you to define the function, you don't need to call it yourself.
