I try to add def checklen(max_list_from_all_plates, listaMain, ListaVal):

My error in code :

Thank you in advance!

Please use the forum post's Code tags around your code to make your code legible.

You should state what your issue is, what error you get on what line, etc. not just "but have some errors"....

I fixed like you was recomending

@coutKateM
So if your code never enters the for mainresult in plateresults it never sets maxelement. Then it tries to print(maxelement), that is undefined, hence the error.

You need to initialize it before the for loop, in case that never gets entered.

This has nothing to do with your __init__(). With it commented out, as you show, all your variables are Python class variables. I doubt that is what you intend, but that's up to you. You don't seem to have used self anywhere. That is surprising, but again up to you.
