[编程题]学分绩点

- 算法知识视频讲解
北京大学对本科生的成绩施行平均学分绩点制（GPA）。既将学生的实际考分根据不同的学科的不同学分按一定的公式进行计算。
公式如下：
实际成绩 绩点
90——100 4.0
85——89 3.7
82——84 3.3
78——81 3.0
75——77 2.7
72——74 2.3
68——71 2.0
64——67 1.5
60——63 1.0
60以下 0
1．一门课程的学分绩点=该课绩点*该课学分
2．总评绩点=所有学科绩点之和/所有课程学分之和
现要求你编写程序求出某人A的总评绩点（GPA）。
输入描述:
第一行 总的课程数n（n<10）； 第二行 相应课程的学分（两个学分间用空格隔开）； 第三行 对应课程的实际得分； 此处输入的所有数字均为整数。
输出描述:
输出有一行，总评绩点，精确到小数点后2位小数。（printf("%.2f",GPA);）
示例1
输入
5 4 3 4 2 3 91 88 72 69 56
输出
2.52

python solution
60分以下是0不是0.1，千万别看错了。。妈的，查了半天最后发现这里错了。
代码通过：
a,b,c=input(),list(map(int,input().split())),list(map(int,input().split()))
total=0
for i,v in enumerate(c):
if 90<=v<=100:total+=b[i]*4
elif 85<=v<=89:total+=b[i]*3.7
elif 82<=v<=84:total+=b[i]*3.3
elif 78<=v<=81:total+=b[i]*3
elif 75<=v<=77:total+=b[i]*2.7
elif 72<=v<=74:total+=b[i]*2.3
elif 68<=v<=71:total+=b[i]*2
elif 64<=v<=67:total+=b[i]*1.5
elif 60<=v<=63:total+=b[i]*1
else:total+=b[i]*0

这题有毒吧，我本地得出的就是2.68，上传上去就成了2.86，篡改我答案？
另外这题就一个用例。
d = {60:0,64:1,68:1.5,72:2,75:2.3,78:2.7,82:3,85:3.3,90:3.7,101:4}
a,b,j,p = int(input()),list(map(int,input().split())),-1,0
for i in map(int,input().split()):
j,k = j + 1,0
while i >= list(d)[k]:
k += 1
p += d[list(d)[k]] * b[j]
print('{:.2f}'.format(p / sum(b)))

本机c语言环境下结果正确，为什么在这里计算有偏差呢，求大神帮忙解答一下
