Python - 将包含 IP 地址和不同数据的文本文件的列表转换为 CSV

Question

我的任务是从多个文本文件创建 NFS 共享和关联 IP 的列表，并将其保存为 CSV。该文件包含 NFS 共享名称和 IP 以及我不希望包含在 CSV 中的其他数据

文本文件示例:

/vol/vm-01
-sec=sys,rw=10.44.160.133:10.44.160.132:10.44.160.131:10.44.160.130,root=10.44.160.133:10.44.160.132:10.44.160.131:10.44.160.130 /vol/vol01
-sec=sys,rw=10.44.202.39:10.44.202.73,root=10.44.202.39:10.44.202.73

我使用了正则表达式并很容易地过滤掉了 IP，但找不到合并卷名的方法。

# Scrape file for IP's using RegEx
with open('input.txt') as f:
    qlist = [re.findall( r'[0-9]+(?:\.[0-9]+){3}', i ) for i in f.readlines()]
    for x in range(len(qlist)):
        print(qlist[x])

示例输出:

['10.44.160.133', '10.44.160.132', '10.44.160.131', '10.44.160.130', '10.44.160.133', '10.44.160.132', '10.44.160.131', '10.44.160.130'] ['10.44.202.39', '10.44.202.73', '10.44.202.39', '10.44.202.73']

期望的输出:

['vm-01', '10.44.160.133', '10.44.160.132', '10.44.160.131', '10.44.160.130', '10.44.160.133', '10.44.160.132', '10.44.160.131', '10.44.160.130'] ['vol01', '10.44.202.39', '10.44.202.73', '10.44.202.39', '10.44.202.73']

Answer 1

这是完成这项工作的一种方法:

import re

qlist = []
with open('input.txt') as f:
    for line in f.readlines():
        tmp = []
        # search the volume name
        m = re.search(r'/vol/(\S+)', line)
        tmp.append(m.group(1))
        # loop on all IPs
        for i in re.findall( r'[0-9]+(?:\.[0-9]+){3}', line ):
            tmp.append(i)
        qlist.append(tmp)
for x in range(len(qlist)):
    print(qlist[x])

输出:

['vm-01', '10.44.160.133', '10.44.160.132', '10.44.160.131', '10.44.160.130', '10.44.160.133', '10.44.160.132', '10.44.160.131', '10.44.160.130']
['vol01', '10.44.202.39', '10.44.202.73', '10.44.202.39', '10.44.202.73']
