python csv contactenation问题

Question

HI我试图将3列合并到csv文件中并且我得到一个IndexError：list index超出范围。我有9列，分隔符是|

import csv

f = open('C:\\diners\\bacon.csv')
csv_f = csv.reader(f)
attendee_emails1 = []
for row in csv_f:
   attendee_emails1.append(row[5]+row[6]+row[7])

print (attendee_emails1)  

我做得不对？

Answer 1

在将文件对象传递给reader方法时，还需要指定分隔符。

csv_f = csv.reader(f, delimiter="|")

代码：

import csv
f = open('/home/avinash/Desktop/dh.csv')
csv_f = csv.reader(f, delimiter="|")
attendee_emails1 = []
for row in csv_f:
   attendee_emails1.append(row[5]+row[6]+row[7])

print (attendee_emails1) 

示例：的

$ cat dh.csv
1|2|3|4|5|6|7|8|9
$ python script.py
['678']
