计算分数算法
1.最简单的计算分数
correct_answer=["A","B","C"]
my_answer=["A","C","D"]
mark=0
i=0
while i<3:
if correct_answer[i]==my_answer[i]:
mark+=1
i=i+1
print(mark)
#运行结果：
1
2.分模块计算
correct_answer=["A","B","C"]
my_answer=["A","C","D"]
mark=0
i=0
base_mark=0
promote_mark=0
major_mark=0
while i<3:
if i<=1:
if correct_answer[i]==my_answer[i]:
base_mark+=1
mark=mark+1
else:
if correct_answer[i]==my_answer[i]:
mark=mark+1
i=i+1
print("总分数为：",mark)
print("基础分数为：",base_mark)
3.分三个模块进行计算
correct_answer=["A","B","C","D","A","B","C","D","A","B"]
my_answer=["A","C","C","A","C","D","C","C","D","A"]
mark=0
i=0
base_mark=0
promote_mark=0
major_mark=0
promote_mark=0
major_mark=0
while i<=9:
if i<=3:
if correct_answer[i]==my_answer[i]:
base_mark+=1
mark=mark+1
elif i<=6:
if correct_answer[i]==my_answer[i]:
mark=mark+1
promote_mark+=1
else:
if correct_answer[i]==my_answer[i]:
mark=mark+1
major_mark+=1
i=i+1
print("总分数为：",mark)
print("基础分数为：",base_mark)
print("提升分数为：",promote_mark)
print("专业分数为：",major_mark)
4.html实现表单选项

<label class="layui-form-label">单选框label>
<div class="layui-input-block">

存在的问题是：不能循环遍历出同一科目或者同一考试下的所有题目
