“人生苦短，我用Python”。Python的高效有一部分是跟它豐富的模塊分不開的。Python有很多第三方模塊可以幫助我們完成一些事情，減少開發(fā)時間。

Python pypi庫中一個模塊名字叫“netifaces”，使用C語言寫的一個第三方模塊。可以：

1.獲取本機(jī)的所有網(wǎng)關(guān)

2.獲取本機(jī)所有的接口Interface（網(wǎng)卡NIC）

3.獲取本機(jī)指定接口的詳細(xì)信息，包括IP地址、子網(wǎng)掩碼、廣播地址、MAC地址等

不過遺憾的是這個模塊的功能太有限以及會帶出一些令人困惑的信息，例如Windows系統(tǒng)上的子網(wǎng)掩碼可能不正確等。

PS：要想獲取公網(wǎng)地址，可以使用很多種API，例如：

# Use 3rd party web-sites to get your IP

# Please note that I do not recommend following curl/wget method due to security reasons. You have been warned:

curl ifconfig.me

curl icanhazip.com

curl ipecho.net/plain

curl ifconfig.co

curl http://ip.chinaz.com/getip.aspx

運行截圖如下：

代碼如下：#!/usr/bin/python

最后：不要重復(fù)制造輪子。重復(fù)制造輪子對自己而言，雖然制造的過程是學(xué)習(xí)鞏固的過程，但重復(fù)制造輪子對別人沒有好處，人生苦短，別重復(fù)制造輪子，除非你制造的足夠好。
