有如下程序代码：

import csv    #  ①
headers = ['学号','姓名','分数']
rows = [['202001','张三','98'],
        ['202002','李四','95'],
        ['202003','王五','92']]
with open('score.csv','w',encoding='utf8',newline='') as f : #  ②
    writer = csv.writer(f)   #  ③
    writer.writerow(headers)
    writer.writerows(rows)   #  ④
