Try and except

On step 2, I turn the arguments into floats but I keep getting "Bummer! 'add' returned the wrong number." I tried it out in workspaces and it worked. Why wouldn't it work here?

trial.py 
def add(n1, n2):
    float(n1)
    float(n2)
    return (n1 + n2)

If you just call the float function it won't actually change the variable.

That is important. You must turn them into floats and then return them directly (after adding) like this:

def add(num1, num2):
    return float(num1) + float(num2)

Good luck! ~Alex

Hi Holden,

The issue is that although you ran your arguments through the float() functions, you are still returning the sum of the original arguments. They haven't been permanently converted into floats. There are a few ways to do this, but you could either re-assign the variables, i.e., n1 = float(n1) and then leave your return statement as is. Or you could convert each argument in the return statement itself and add them together.

Good Luck,
