【Python】實現輸出成績最高或最低分的學生姓名以及低於平均分的學生姓名

scores = {"小劉": 45, "小紅": 68, "小米": 96, "小白": 65, "小夢": 75}
highest = max(scores.values())
lowest = min(scores.values())
average = sum(scores.values()) / len(scores)
# print("平均值為："+str(average))
max_keys = [k for k, x in scores.items() if not any(y > x for y in scores.values())]
print('成績最高的是:')
for student in max_keys:
    print(student)
min_keys = [k for k, x in scores.items() if not any(y < x for y in scores.values())]
print('成績最低的是:')
for student in min_keys:
    print(student)


personName = [k for k, v in scores.items() if v < average]
print("低於平均值的學生：")
for student in personName:
    print(student)
