python-在Windows中正确获取MAC地址 [英] python - getting the MAC address properly in Windows

问题描述

我正在使用Windows 7和Python 2.6.我想获取我的网络接口的MAC地址.

I'm using Windows 7 and Python 2.6. I would like to get the MAC address of my network interface.

我尝试使用wmi模块:

def get_mac_address():

    c = wmi.WMI ()
    for interface in c.Win32_NetworkAdapterConfiguration (IPEnabled=1):
        return  interface.MACAddress

但是，在没有Internet连接的情况下执行时会遇到问题.

However, experienced issues when executed without internet connectivity.

我尝试使用uuid模块:

from uuid import getnode 
print getnode()

但是，返回值是MAC地址的48字节表示形式

However, return value is a 48 byte representation of the MAC address

66610803803052

1)如何将给定的数字转换为ff:ff:ff:ff:ff:ff格式?
2)有没有更好的方法来获取MAC地址?

1) How should I convert the given number to ff:ff:ff:ff:ff:ff format?
2) Is there a better way to get the MAC address?

推荐答案

这有效:

>>> address = 1234567890
>>> h = iter(hex(address)[2:].zfill(12))
>>> ":".join(i + next(h) for i in h)
'00:00:49:96:02:d2'

或者:

>>> "".join(c + ":" if i % 2 else c for i, c in enumerate(hex(address)[2:].zfill(12)))[:-1]
'00:00:49:96:02:d2'

或者:

>>> h = hex(address)[2:].zfill(12)
>>> ":".join(i + j for i, j in zip(h[::2], h[1::2]))
'00:00:49:96:02:d2'

首先将数字转换为十六进制，将其填充为12个字符，然后将其转换为一系列的两个字符字符串，然后将其与冒号连接起来.但是，这取决于您的MAC查找方法的准确性.

You first convert the number to hex, pad it to 12 chars, and then convert it to a series of two char strings, and then join them with colons. However, this depends on the accuracy of your MAC-finding method.
