如何在python中将字符串转换为IP地址

Question

how can i convert a string ip address to a decimal number. eg I have a data bytes= b'363,3,1778952384,7076' , here 1778952384 is my ip address and 7076 is my port. How can I convert my IP address to decimal number. below is my code, please help me to solve these problem

/app.py

import socket
from tornado.tcpclient import TCPClient
from tornado import gen

@gen.coroutine
def f(self, message):

    global stream
    client = TCPClient()
    stream = yield client.connect('192.168.8.108', 2620, max_buffer_size=int(1e9))
    msg = '192.168.8.101, 8000'.encode('utf-8')
    yield stream.write(msg)
    data = yield stream.read_bytes(21)
    print("bytes=",data) #bytes= b'363,3,1778952384,7076

Python has an ipaddress module which can handle this sort of thing. It was added to the standard library in Python 3, but should be installable for earlier versions, too.

>>> import ipaddress
>>> print(ipaddress.ip_address(1778952384))
IPv4Address('106.8.168.192')
>>> print(str(ipaddress.ip_address(1778952384)))
'106.8.168.192'

You may also be asking about splitting the string (on b',' since it's a bytestring), getting the right field, and converting it to an int :

data = b'363,3,1778952384,7076'
ipaddress.ip_address(int(data.split(b',')[2]))
