딕셔너리에 저장된 점수 중 최저 및 최고 점수를 삭제하는 프로그램을 만들어보자

scores = {'score1':8.9, 'score2':8.1, 'score3':8.5, 'score4':9.8, 'score5':8.8}

maxScoreKey = ''
for key in scores.keys():
    if scores[key] < minScore:
        minScore = scores[key]
        minScoreKey = key
    if scores[key] > maxScore:
        maxScore = scores[key]
        maxScoreKey = key
del scores[minScoreKey]
del scores[maxScoreKey]
print(f'scores : {scores}')
