Stuck at try and except, need help?

I'm stuck at the try and except part of the python beginner course for a while. I know i'm doing something wrong but just can't figure it out. Could someone please send me the solution or explain this to me please?

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

except ValueError:
    return None

else:
    return num1 + num2

The issue you are having is understanding scope. Here is an article on the subject https://www.python-course.eu/python3_global_vs_local_variables.php

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