it easy check if element of list in list using any() : any(elem in list2 elem in list1) but there anyway idiomatic way return first element found? i'd prefer one-line solution rather than: for elem in list1: if elem in list2: return elem this answer similar an answer on a similar question , @jamylak goes more detail of timing results compared other algorithms. if want first element matches, use next : >>> = [1, 2, 3, 4, 5] >>> b = [14, 17, 9, 3, 8] >>> next(element element in if element in b) 3 this isn't efficient performs linear search of b each element. create set b has better lookup performance: >>> b_set = set(b) >>> next(element element in if element in b_set) if next doesn't find raises exception: >>> = [4, 5] >>> next(element element in if element in b_set) traceback (most recent call last): stopiteration you can give default return instead, e.g. none . c...
