Hi guys!
I am trying to create an optimized script but I have a problem to extract the index of a list that countains “Level”.
I have tried the string.contains solution and indexOf too but when I run the script the index generated is “-1” and I don’t understand why!
I’m trying to understand what you want to achieve … do you mean something like this?
input = IN[0]
testvalue = IN[1]
output = []
a = 0
for i in input:
if i == testvalue:
output.append(a)
a = a+1
#Assign your output to the OUT variable.
OUT = output

Actually I want to replace and Item At index but the problem is that I can’t have the “List index” that contains “LEVEL”
That’s what I want to achieve :
You’re checking elements against a string. You need to first determine what category the elements are. Then you can replace any Levels with the level name.
Element.Category is from Rhythm.

Nop 
I just want the script to give me the index 0 if Level is in “0 List” and 1 if Level is in “1 List”
If you’re trying to replace the levels with their names then a mask is your best option. If you really need the index you can search for lists that contain Levels.

You forgot to indent the 10 an 11 lines in your script. Just select this two lines and press Tab.
if isLevel = True
should be
if isLevel == True
Can you show the warning you’re getting?
Try Append instead of Add.
Wrong Result 
Check your code again. You must be mistyping something somewhere.
list = IN[0]
test = IN[1]
finalList = []
for index in range(0,len(list)):
level = list[index]
isLevel = False
for item in level:
if item == test:
isLevel = True
if isLevel == True:
finalList.append(index)
OUT = finalList
