This isn't a list in any sense that Python will recognise. Can you show us the actual data structures please? > if teststring in all_types: This would only work if teststring was exactly equal to a whole string in your list, partial string matches only work against a single string: >>> if "fred" in ["fred", "jack"]: print True True >>> if "red" in ["fred", "jack"]: print True >>> >>> for item in ["fred", "jack"]: >>> if "red" in item: print item ... fred >>> > if teststring in all_types.type: No idea what you think this would do. lists don't have a type attribute and you can't access bits of strings that way either. What Python tutorial are you reading? Almost all the tutorials cover string searching and list access. > should i use lambda Almost certainly not. Why do you think lambda would be useful here?
