looks good but its not...

Not sure about the final return, should it be return (num) with an num=num1+num2 or does return num1+num2 handle that? ORRRRR should it be return (num1+num2). Why's and why's not? Thank you!

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

Hi there.

Your code is fine, what prevents it from passing is the indentation, you see, indentation is a big part of Python's syntax.

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

Shift the indentation of all lines of your code after line 1 one level to the right, and now it should be fine.
