从Python（Selenium）中的CSV文件发布拉取列表

我的代码接受输入并成功写入“data.csv”文件，但只要输入了多个数字作为初始输入（例如“98765 12345”），我就会在最后一行得到

索引器：列表索引超出范围

有人能看出我哪里做错了吗

x = raw_input('Enter numbers separated by a space: ')
new_FONs = [[int(i)] for i in x.split()]

with open('data.csv', 'a+') as f:
    writer = csv.writer(f)
    writer.writerows(new_FONs)

with open('data.csv', 'r') as f:
    all_FONs_str = [line.split() for line in f]
    all_FONs = [[int(FON[0])] for FON in all_FONs_str]

for FON in new_FONs:

    # Count the occurence of this number in the CSV file
    FON_count = all_FONs.count(FON)

    if FON_count == 1:
        print('once')

    elif FON_count == 2:
        print('twice')

将最后一个循环限制为倒数第二个元素应该做到：

x = raw_input('Enter numbers separated by a space: ')
new_FONs = [[int(i)] for i in x.split()]

with open('data.csv', 'a+') as f:
    writer = csv.writer(f)
    writer.writerows(new_FONs)

with open('data.csv', 'r') as f:
    all_FONs_str = [line.split() for line in f]
    all_FONs = [[int(FON[0])] for FON in all_FONs_str[:-1]]

all\u FONs\u str

的最后一个元素是什么？@JuanC应该只是一个数字作为字符串？@bboooy在英国不是。您应该查看csv文件本身，或者在最后一行之前打印（all_FONs_str）以查看问题。我在评论中提供的链接将解决此问题。@Chris我认为这是因为它在csv文件中添加了一个空白的额外行。。。由于某些原因，当我做一个for循环时，它从最后一个值运行到第一个，这是遇到空白。有办法解决这个问题吗？将为原始问题添加for循环
