Question

所以我打开了我的文件并使用readlines（）模块将每一行拆分成一个列表，但我试图从readlines（）中获取每个源IP，src端口，dest IP和dest端口。基本上我被要求做的是：＆＃34;打开提供的转储文件并拆分src和dest IP以及src和dest端口＆＃34;的每一行。此外，＆＃34;创建一个名为Hosts的字典;主机的密钥将是从文件解析的IP（src和dest）。每个键的值将是一个两元素列表，其中第一个项目是IP是源的次数，秒是IP是目标的次数＆＃34;。

以下是已解析文件的一部分......

08:43:56.558781 IP 192.168.233.128.56779 > 50.116.53.73.80: Flags [S], seq 3055452145, win    29200, options [mss 1460,sackOK,TS val 82505 ecr 0,nop,wscale 10], length 0

仅供参考，文件的格式如下：

IP（source.Sourceport）＆gt; （dest.Destport）

这是我到目前为止所做的：

import os

while True:
try:
    f = open(os.path.expanduser("~/Documents/Pys/ascii_dump.txt"))
    print ("It Opened!")
    break
except:
    print ("Cannot Open!")
    break

lines = f.readlines()

UPDATE 现在我正在寻找将一个字符串（一行）拆分为另一个字符的最佳方法。所以说把它分成一个＆＃34;：＆＃34;到下一个＆＃34;：＆＃34;。

Answer 1

我认为您需要查看字符串的拆分方法

f = open('data.txt', 'r')
lines = f.read()
lines = lines.split("\n")
print(lines)
for line in lines:
    line = line.split()
    if len(line) > 0:
        srcIp = line[2]
        dstIp = line[4]
        print(srcIp.split('.'),dstIp.split('.'))

给出：

['192', '168', '233', '128', '56779'] ['50', '116', '53', '73', '80:']
['50', '116', '53', '73', '80'] ['192', '168', '233', '128', '56779:']
['192', '168', '233', '128', '56779'] ['50', '116', '53', '73', '80:']
['192', '168', '233', '128', '56779'] ['50', '116', '53', '73', '80:']
['50', '116', '53', '73', '80'] ['192', '168', '233', '128', '56779:']
['50', '116', '53', '73', '80'] ['192', '168', '233', '128', '56779:']
['192', '168', '233', '128', '56779'] ['50', '116', '53', '73', '80:']
['192', '168', '233', '128', '56780'] ['50', '116', '53', '73', '80:']

Python-拆分src IP，src端口，dest IP，dest端口并创建字典
