python读取csv文件

import csv
csv_file = '/路径/'
with open('csv_file','r') as csvfile:
    reader = csv.reader(csvfile)
    data = [row for row in reader]
data[1:]//get rid of the first row-data[0]
        

我的csv文件内容如下(此处只列出3行)：想要获取该csv文件的第一列关于视频id的名称，并按行存入txt文件。

id           subject     scene      actions     length

46GP8    HR43       kitchen    window    a person cooks food on a stove before looking out of a window.

N11GT   0KZ7        Stairs       floor         person at the bottom of the staircase shakes a blanket out.

......

代码如下：

import csv
csv_file = '/文件路径/'
fi = open('id_lst.txt','w') 
with open(csv_file,'r') as f:
    reader = csv.DictReader(f)
    for row in reader:
        actions = row['id'].split(';')
        fi.writelines(actions)
        fi.write('\n')
fi.close()
