Find and Replace Pattern - LeetCode

필터 함수를 활용해서 푸는 방법이 있길래 따라 해 봄.

class Solution:
    def findAndReplacePattern(self, words: List[str], pattern: str) -> List[str]:
        def match(word):
            m1, m2 = {}, {}
            for w, p in zip(word, pattern):
                if w not in m1:
                    m1[w] = p
                if p not in m2:
                    m2[p] = w
                if (m1[w], m2[p]) != (p, w):
                    return False
            return True
        
        return filter(match, words)
