Extract list of ONLY non repeated items

Hello everyone,

I have a list : {“A”,“B”,“D”,“E”,“B”,“D”} and I’d like to extract a list of ONLY non repeated items, in this case only A ad E. How can I achieve that within Dynamo or Python. I’ve tried with Python, importing collection counter but it did not work. please help. Thanks in advance!

Hi @moughit.bouchaara

Here is one of the possible way…

Thanks @Kulkul ! Great. I was wondering how we could do that with python (1 node), for instance with the counter collection. My script is already huge. Otherwise, I will use your solution, thanks again.

Could you send your piece of code so that we can quickly see what this issue is about?
