Hi, I want to check if a list contains 2 specific items, and I want the result to return “True” only if it contains both items: [image] Thanks in advance for any help, Zirjay

@zilong245 Actually I don’t think String.Contains will work. You could try this python code: [image] OUT=[] for lst in IN[0]: if all (item in lst for item in IN[1]): OUT.append(True) else: OUT.append(False)

Is there an opposite of the List.Contains node?
