need help

I need the code to finish this challenge

this is what is so far

def add(x, y): # number 1 and 2 return x + y # number 3 def add(x , y): a = float(x) b = float(y) return a + b return(float(num1) + float(num2))

trial.py 
def add(x, y):    # number 1 and 2
    return x + y   # number 3
def add(x , y):
    a = float(x)
    b = float(y)
    return a + b
return(float(num1) + float(num2))

You have two add functions. There should be only one:

def add(x, y):
    return float(x) + float(y)

Hey there Daniel,

you almost got it but you still have to add the try, except and else blocks. Also note that you can remove the first function and take care that you indent correctly. You have to change your arguments to floats in the try block and catch a possible ValueError.

Like so:

def add(x , y):
    try:
        a = float(x)
        b = float(y)
    except ValueError:
        return None
    else:
        return a + b

I hope that helps! :)
