【问题描述】输入若干成绩值，以回车作为输入结束。输出最高的三个成绩值，以及最大值和最小值。
【输入形式】"Input a score(end of enter):"

【输出形式】"Top 3 scores:" "max={},min={}"

【输入输出示例】


```python

Input a score(end of enter):9

Input a score(end of enter):4.6

Input a score(end of enter):8.2

Input a score(end of enter):1

Input a score(end of enter):4

Input a score(end of enter):7

Input a score(end of enter):

Top 3 scores:

max=9,min=1

```

s_lst = []
while True:
    s = input("Input a score(end of enter):")
    if s == "":
        break
    else:
        s_lst.append(float(s))

for i in range(len(s_lst)):
    if int(s_lst[i]) == s_lst[i]:
        s_lst[i] = int(s_lst[i])

# print(s_lst)
s_lst.sort(reverse=True)
print("Top 3 scores:")
for s in s_lst[:3]:
    print(s)
print("max={},min={}".format(s_lst[0],s_lst[-1]))



s_lst = []
while True:
    s = input("Input a score(end of enter):")
    if s == "":
        break
    else:
        s_lst.append(float(s))

print(s_lst)
s_lst.sort(reverse=True)
print("Top 3 scores:")
for s in s_lst[:3]:
    print(s)
print("max={},min={}".format(s_lst[0],s_lst[-1]))
