好的，我来帮您改一下变量名：

dict_scores = {} 
list_max_scores = [] 
list_table_header = [['班级', '学号', '姓名', '测试1（百分制）', '测试2（百分制）', '测试3（百分制）', '测试4（百分制）', '总分', '备注']]

with open('total.csv', mode='r') as f:     
    r = f.readlines()     
    n = 0     
    for l in r:         
        list_line = l.split(',')         
        list_line[-1] = list_line[-1][:-1]         
        if n == 0:             
            for t in list_line[3:]:                 
                num = ''                 
                for s in t:                     
                    if s.isdigit():                         
                        num += s                     
                    if s == '.':                         
                        break                 
                list_max_scores.append(int(num))         
        else:

            dict_scores[list_line[2]] = list(map(int, [list_line[3], list_line[4], list_line[5], list_line[6]]))         
        n += 1 

for t, v in dict_scores.items():     
    len_scores = len(v)     
    for k in range(len_scores):         
        v[k] = (v[k] / list_max_scores[k]) * 100 // 1     
    total_score = sum(v)     
    v.append(total_score)

row_num = 1 
for t, v in dict_scores.items():     
    for score in v:         
        score = str(score)         
        list_table_header[row_num + 1].append(score)     
    row_num += 1 

list_table_header.pop(1) 

with open('最终成绩单.csv', mode='w') as f:     
    for i in list_table_header:         
        line = ','.join(i)         
        line += '\n'         
        f.write(line)         
        print(i)
