import csv
import random

with open ('scores.csv', 'w') as file:
    writer = csv.writer(file, delimiter = '|')
    writer.writerow(['姓名', '语文', '数学', '英语'])
    names = ['关羽', '张飞', '赵云', '马超', '黄忠']
    for name in names:
        scores = [random.randrange(50, 101) for _ in range(3)]
        scores.insert(0, name)
        writer.writerow(scores)

    #从csv文件读取数据
with open('scores.csv', 'r') as file:
     reader = csv.reader(file, delimiter = '|')
     for data_list in reader:
        print(reader.line_num, end = '\t')
        for elem in data_list:
            print(elem, end = '\t')
        print('')
