I am sure I did it right but why it did not work?

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

In short: indentation error. Under your try block the first two lines need to be indented. I've modified your code simply for indentation purposes. Take a look:

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

Remember python loves its whitespace and is very picky about indentation.

I got it, thank's! :)
