프로그래머스

 

def solution(name, yearning, photo):
    answer = []
    a_dict = {}

    for i in range(len(name)):
        a_dict[name[i]] = yearning[i]

    for i in range(len(photo)):
        sum_a = 0
        for j in range(len(photo[i])):
            if photo[i][j] in name:
                sum_a += a_dict[photo[i][j]]
        answer.append(sum_a)

    return answer

 

 

-> 다른 사람의 풀이

def solution(이름, 점수, 사진):
    return [sum(점수[이름.index(j)] for j in i if j in 이름) for i in 사진]

def solution(name, yearning, photo):
    dictionary = dict(zip(name,yearning))
    scores = []
    for pt in photo:
        score = 0
        for p in pt:
            if p in dictionary:
                score += dictionary[p]
        scores.append(score)
    return scores

⭐️파이썬 dict, zip 함수를 사용하여 name과 yearning을 합쳐주기

 

그리고 꼭 i, j 숫자로 표현할 필요 x
