Try and Except block syntax errors?

Hello,

I have entered the following code below for this problem. I think something is wrong with my syntax, but I am not sure what. Did I use the try and except functions correctly?

def add(sex, age): try:
return(float(sex)+float(age)) except ValueError: return(None)

trial.py 
def add(sex, age):
try:  
  return(float(sex)+float(age))
except ValueError:
  return(None)

Hey Jacob,

you have to indent everything inside your add function and also note that return is no method so you don't have to use parentheses for your return statement.

About the challenge: The challenge wants you to change your parameters to floats in the try block and then return the result in the else block.

So your code should end up like this:

def add(sex, age):
  try:  
    sex = float(sex)
    age = float(age)
  except ValueError:
    return None
  else:
    return sex + age

I hope everything makes sense for you and that you're able to solve the challenge! :)

Good luck!

Thank you! I didn't realize that return was not a function and that the parameters should be listed on separate lines.
