Check what you do inside your while and after it. You have to change that part at least for it to work.

Hi again Chrono79, sorry for all the non-sense. Well, I fix what you told me and I run the 3 number sequence that you show me, I fix a line that was causing me trouble with it and now my code works fine.... but still I'm getting some incorrect answers on the "attemp mode".. I guess I'm just dumb with this... anyway thanks!! :D

The first thing I see wrong in your code is the function definition: def find_missing (list): change list for a there. Then read the description again carefully, you're overcomplicating things.

Please, when posting code use markdown formatting otherwise all indentation is lost and in Python, where it matters, your code becomes hard to read.

Thanks Chrono79!

You need to return the function call to narc inside narcissistic. If there is no explicit return in your function, the default returned value is None.
To increase the readability of comments or descriptions, see this page in the github wiki.

Are you calling that function from inside narcissistic function?

Thanks friend, now it works!

You're printing the output instead of returning it.

My Python code for IQ Test Kata works like a charm, all the answers are the same as the sample test and final attempt but it's keep me give me an error "None should be x" and my answer (x) is the same as the one provided for the try
