我開始學習編程，我正在嘗試編寫一個簡單的解析器，但我很困惑。如果有人幫助我，我會很高興。文件.txt# Masscan 1.0.3 scan initiated Sun Dec 23 23:00:31 2018# Ports scanned: TCP(1;80-80) UDP(0;) SCTP(0;) PROTOCOLS(0;)Host: 192.168.1.1 () Ports: 80/open/tcp////Host: 192.168.1.1 () Ports: 801/open/tcp////Host: 192.168.1.2 () Ports: 801/open/tcp////Host: 192.168.1.2 () Ports: 445/open/tcp////Host: 192.168.1.3 () Ports: 80/open/tcp////Host: 192.168.1.3 () Ports: 8080/open/tcp////Host: 192.168.1.3 () Ports: 21/open/tcp////# Masscan done at Sun Dec 23 23:00:45 2018我想以一種格式接收數據：192.168.1.1 80, 801192.168.1.2 801, 445192.168.1.3 80, 8080, 21腳本文件#!/usr/bin/env pythonimport sys, re, osports = []ip = Nonewith open('mres.txt','r') as f:for elem in f.readlines(): if not elem.startswith('#'): if ip != None: if elem.split(' ')[1] == ip: ports.append(elem.split(' ')[3].split('/')[0]) continue else: print(ip + str(ports)) ports=[] else: #print('Unic: '+str(ip) + ' port: '+ str(elem.split(' ')[3].split('/')[0])) ip = elem.split(' ')[1] ports.append(elem.split(' ')[3].split('/')[0])

你最好使用dict來處理數據：1）IP可以是Dict中的key 2）List可以是Dict中的值。
如果需要，我可以為您創(chuàng)建示例代碼。

這將操作您的數據，并打印您想要的輸出。我已經嘗試在下面的評論中盡可能地解釋它，但請?zhí)岢鋈魏尾磺宄膯栴}。
from collections import defaultdict
import socket
# build a dictionary of ip -> set of ports
# default dict is cool becasue if the key doesn't exist when accessed,
# it will create it with a default value (in this case a set)
# I'm using a set because I don't want to add the same port twice
ip_to_ports = defaultdict(set)
with open('mres.txt') as fp:
for line in fp:
# grab only the lines we're interested in
if line.startswith('Host:'):
parts = line.strip().split()
ip = parts[1]
port = parts[-1]
# split it by '/' and grab the first element
port = port.split('/')[0]
# add ip and ports to our defaultdict
# if the ip isn't in the defaultdict, it will be created with
# an empty set, that we can add the port to.
# if we run into the same port twice,
# the second entry will be ignored.
ip_to_ports[ip].add(port)
# sort the keys in ip_to_ports by increasing address
for ip in sorted(ip_to_ports, key=socket.inet_aton):
# sort the ports too
ports = sorted(ip_to_ports[ip])
# create a string and print
ports = ', '.join(ports)
print(ip, ports)
