Question

我有两个带有ip-Addresses的文件，我试图查看文件1中的哪些地址不在文件2中。我只是不能让它工作，我做错了什么？我得到了以下代码：

access = []   
with open("C:\\users\\joey\\desktop\\access.log",'r') as bestand:
    for line in bestand:
        try:
            splittedline = line.split('sftp-session')[1].split("[")[1].split("]")[0]
        except Exception:
            continue
        access.append(splittedline)


nodes = []
with open("C:\\users\\joey\\desktop\\exit_nodes.csv",'r') as bestand1:
    for line in bestand1:
        nodes.append(line)


setA = set(access)
setB = set(nodes)
listC = list(setB - setA)

print listC

输出:(只是一小部分）

Answer 1

在将每行添加到列表中之前，请尝试删除每行的换行符。我认为你的第二个清单中的换行符正在干扰比较。

>>> a = "one two three\n"
>>> a
'one two three\n'
>>> a.rstrip("\n")
'one two three'
>>> a
'one two three\n'

Answer 2

我认为分割线的部分是问题：

splittedline = line.split('sftp-session')[1].split("[")[1].split("]")[0]

我尝试了一些示例输入 access.log ：

1.1.1.2
1.1.1.3

和 exit_nodes.csv ：

1.1.1.1
1.1.1.2
1.1.1.3
1.1.1.4

并使用您的（修改过的）脚本（使用.strip()删除换行符）

access = []   
with open('access.log', 'r') as a:
    for line in a:
        access.append(line.strip())

nodes = []
with open('exit_nodes.csv', 'r') as b:
    for line in b:
        nodes.append(line.strip())

setA = set(access)
setB = set(nodes)
listC = list(setB - setA)

print listC

它产生正确的输出，exit_nodes.csv中的所有内容，但不在access.log中：

>>> 
['1.1.1.4', '1.1.1.1']

Answer 3

我猜你的输入是sftp-session[127.0.0.1] 您应该使用正则表达式来解析数据。

import re

access = []   
with open("C:\\users\\joey\\desktop\\access.log",'r') as bestand:
    for line in bestand:
        re_match = re.search('sftp-session\[\s*(\d+\.\d+\.\d+\.\d+)\s*\]', line)
        if re_match:
            access.append(re_match.group(1))
        else:
            continue

这样您就可以确保在阵列中获得100％正确的数据。正如obscurite所述，您的问题可能是输出中的换行符\n。
