在python中将IP地址转换为字节 [英] Converting IP address into bytes in python

问题描述

假设我在python中有一个IP地址

Say i have an IP address in python

addr = '164.107.113.18'

如何将IP地址转换为4个字节？

How do i convert the IP address into 4 bytes?

推荐答案

使用 Maciej Gol的回答，但这是另一种方式：

Go with Maciej Gol's answer, but here's another way:

ip = '192.168.1.1'
ip_as_bytes = bytes(map(int, ip.split('.')))

编辑：糟糕，这只是Python 3.X。对于Python 2.X

EDIT: Oops, this is Python 3.X only. For Python 2.X

ip = '192.168.1.1'
ip_as_bytes = ''.join(map(chr,map(int,ip.split('.'))))

你最好过的时候但是，鉴于其效率，使用套接字模块：

You're better off using the socket module, however, given its efficiency:

>>> timeit.timeit("socket.inet_aton('164.107.113.18')",setup='import socket')
0.22455310821533203
>>> timeit.timeit("''.join(map(chr,map(int,'164.107.113.18'.split('.'))))")
