1. python from collections import defaultdict import re class Solution: def mostCommonWord(self, paragraph: str, banned: List[str]) -> str: dict=defaultdict(int) paragraph=re.sub(r'[^\w]',' ',paragraph) # print(paragraph) for p in paragraph.lower().split(): if p not in banned: dict[p]+=1 return max(dict,key=dict.get) cnt=collections.Counter(dict) 해서 return cnt.most_common(1)[0][0]으로 가져오는 방법도 있다 ..
