csv 存储有空行 解决方案

import csv
with open('test2.csv','w',encoding='utf-8',newline='')as f:
    write = csv.writer(f)

    # 先写入columns_name
    write.writerow(['index','a_name','b_name'])
    # 写入多行用writerows
    write.writerows([[0,1,3],[1,2,3],[2,3,4]])

import csv

with open('test2.csv','r',encoding='utf-8',newline='')as f:
    reader = csv.reader(f)
    for line in reader:
        print(line)
