Hi Everyone! I want to create a new list from the original list with one condition, New lists are create up of lists with false conditions… Thanks in advance! [image]

This is much easier with python, but it can be done with nodes only. You just have to get the indices and shift them to create a sequence between true values. [image]

@lebinhx3c2012 you can use list filterbyboolmask to get new list. [image] Hope this helps.

Thanks for your answer, but I want creates a new list added by lits[ 1] and list [2] [image]

Hi @shahid.shaikh_C3D its new list is create up of list [1…9] and list [10…15] … [image]

A CSV file is missing for the above script to run, anyway what i understood if i am correct is you want to create a new list from [1…9] and [10…15] based on true value (i.e. if it contains pole omit it). Based on that see if this helps [image]

I think you just need to filter those lists. [image] If not, you’re going to need to show us your expected list output. It’s hard to understand exactly what you’re after.
