Index of duplicate items in list

[EzDoesIt]

Hi,

I found this one from Vikram
When i try to use it the code block 0…List.Count(1)-1; it has no input connector
Wat i am trying to do is get the index value of all double items in the list

It is the letter “L” lowercase not a 1

The item in the List.Count method should be a lowercase L (l) or some other series of letters, not a 1 or some other number. Personally I like using lst in a Python and Design Script context.

0..List.Count(lst)-1;
