Is there a way to get to get help (answers) to code challenges without having to ask and wait?

I realize the benefit of trudging along via trial and error in most cases and I've done that up to this point. But, it can be extremely frustrating when the code challenge seemingly is asking me to extrapolate already unfamiliar concepts in order to complete it. It's not extremely helpful to repeatedly be told "bummer, try again."

In TTH, best way to learn something completely is watching the videos until you understand all of the mentioned concepts.

Another option is consulting google. Probably, someone have faced your problem before.

Last option is asking yourself.

def add(a, b):
  try:
    a = float(a)
    b = float(b)
  except ValueError:
    return None
  return a + b

Thanks for your response. I've rewound most videos probable 25-30 times, lol. You're obviously much more advanced, as I would have never written it that way since the challenge says to use "else" and no where in the python track so far have I seen the arguments (a and b) broken up like that. I guess that's the nice thing and frustrating thing about coding, multiple methods possible.

In programming, there are unlimited possibilities. That's because everybody thinks differently.

Asking is the best way.

Dane,

I too am struggling with this! I'm not sure why TTH doesn't have a "hint" button or anything to help users understand why our challenge code isn't working. It's really frustrating and time consuming to have to ask a forum for help on a challenge
