Quiz: Try and Except, Q2 - How to convert Python function return to float

First part of question:

I need you to make a new function, add. add should take two arguments, add them together, and return the total.

Second part of the question (which I can't figure out)

Let's make sure we're always working with floats. Convert your arguments to floats before you add them together. You can do this with the float() function.

trial.py 
def add(one, two):
    return(one + two)

For you to return the floated sum of the variables one and two you would need to write it like this.

return float(one+two)

or you could write it like this.

return float(one) + float(two)

How do I use Float() to convert the argument though? I tried this originally and it did not work.

def add(one, two):
    float(return(one + two))

def add(num1, num2): return float(num1) + float(num2) total = add(3,5)
