python - 如何以普通字符显示ip

Question

我的脚本有问题。为了进行测试，我想打印一个 src 和 dst ip 地址，但显示的字符很特殊，经过多次研究后我仍然不明白为什么...... 我确定这是一个简单的问题，但我没有明白...

这是输出:

这是我的脚本:

import pcapy
import dpkt
from threading import Thread
import re
import binascii

liste=[]
listip=[]
piece_request_handshake = re.compile('13426974546f7272656e742070726f746f636f6c(?P<reserved>\w{8})(?P<info_hash>\w{20})(?P<peer_id>\w{20})')
piece_request_tcpclose = re.compile('(?P<start>\w{12})5011')

sniffer = PieceRequestSniffer()
sniffer.start()

首先，导入socket，然后使用:

src_ip = socket.inet_ntoa(ip.src)
dst_ip = socket.inet_ntoa(ip.dst)
