Need help with Trial.py quiz in the Python Basic course.

I'm not able to figure out what I'm doing wrong with this code. I will appreciate any assistance. Thank you.

trial.py 
def add(num1, num2):
    try:
        int(num1)
        int(num2)
    except ValueError:
        return()
    else:
        return(float(num1)+float(num2))

There are two problems.

  1. You are converting num1 and num2 into integers in the try block. The questions says to convert the two numbers into floats in the try block.
  2. If a ValueError occurs, the question says to return None. You literally returned nothing. What you need to do is put return None inside the except block.

Here is the code that allowed me to pass the challenge.

def add(num1, num2):
    try:
        num1 = float(num1)
        num2 = float(num2)
    except ValueError:
        return None
    else:
        return num1 + num2

Hope this helps, and feel free to ask any questions.
