Python打印本机IP

两行代码：

import socket
print socket.gethostbyname(socket.gethostname())

上面这个东西只能在windows上使用，估计下面这个方法到处都能用：

#!/usr/bin/env python

import socket

def getip():
	try:
		s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
		s.connect(('www.baidu.com', 0))
		ip=s.getsockname()[0]
	except:
		ip=""
	finally:
		s.close()
		return ip

if __name__=='__main__':
	print getip()

还找到一个用于获取外网IP的方法：

import re,urllib2
class Getmyip:
    def getip(self):
        try:
            myip = self.visit("http://www.ip138.com/ip2city.asp")
        except:
            try:
                myip = self.visit("http://www.bliao.com/ip.phtml")
            except:
                try:
                    myip = self.visit("http://www.whereismyip.com/")
                except:
                    myip = "So sorry!!!"
        return myip
    def visit(self,url):
        opener = urllib2.urlopen(url)
        if url == opener.geturl():
            str = opener.read()
        return re.search('\d+\.\d+\.\d+\.\d+',str).group(0)
getmyip = Getmyip()
localip = getmyip.getip()
print localip
