Slightly modified your solution: def isAlienSorted(self, words: List[str], order: str) -> bool: order = { val: index for index,val in enumerate(order)} def lexico(word1, word2): for i in range(min(len(word1), len(word2))): if word1[i] != word2[i]: return order[word1[i]] < order[word2[i]] return len(word1)
