统计成绩等级 分类等级

有个列表里面都是班里的分数
按照成绩分出等级
怎么可以得知优秀有几名？良有几名？及格几名



```python
import random
total_number = input("输入班级人数:")
grade_list = []
i = 0
while i < int(total_number):
    card_number = random.randint(0, 100)
    grade_list.append(card_number)
    i += 1
print("随机生成的班级分数列表:", grade_list)
excellentGrade = input("优秀分数线：")
goodGrade = input("良好分数线：")
passingGrade = input("及格分数线：")
excellentNumber = 0
goodNumber = 0
passingNumber = 0
failNumber = 0
for j in grade_list:
    if j >= int(excellentGrade):
        excellentNumber += 1
    elif j >= int(goodGrade):
        goodNumber += 1
    elif j >= int(passingGrade):
        passingNumber += 1
    else:
        failNumber += 1
print(excellentNumber, goodNumber, passingNumber, failNumber)

```
