Are they always at position 2 and 3?

What exactly are you wanting to do? You’re already getting the index of each item. Can you show us what your expected outcome would be?

Hi @Eng.Minh,
Welcome to the Dynamo community.
Try copy-pasting the code as shown below into a Python node in your graph.
IndexOf (No Repeat).dyn (5.4 KB)

OUT = []
for i,x in enumerate(IN[1]):
	allIndices = [j for j,y in enumerate(IN[0]) if y == x]
	if allIndices:
		try:
			k = IN[1][:i].count(x)
			OUT.append(allIndices[k])
		except:
			OUT.append(allIndices[-1])
	else:
		OUT.append(-1)
