Float, float on - changing function to float before adding

I also tried it as so:

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

AND

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

this seems pretty straight forward? What am I doing wrong. I am converting the arguments into floats before adding. No?

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

We don't do the conversion of the floats in the definition of the parameters of the function. Instead we take the float of each number and add it together. Here's my end code to clarify what they're looking for:

def add(x,y):
  try:
    return float(x) + float(y)
  except ValueError:
    return None

Note: this is for challenge 3 of 3.

Hi,

the float function takes only **one argument.

The challenge is asking you to return the floated version of your arguments so you need to do something like this:

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