I've been trying to get the MAC address of the machine I'm using with netifaces and uuid python module. I used the following code :

import netifaces
from uuid import getnode as get_mac
interfaces = netifaces.interfaces()
print(interfaces)
for interface in interfaces:
 print(netifaces.ifaddresses(interface))
 addr = netifaces.ifaddresses(interface)[netifaces.AF_LINK]
 print(addr)
mac = get_mac()
mac_up = ':'.join(("%012X" % mac)[i:i+2] for i in range(0, 12, 2))
print(mac_up)

The output is :

['1D16676A-E736-4270-9CDC-0DCDC7B75085', '5C842FD7-362A-4303-BC0D-F39D143D8AF6', '12C9575B-0038-4DCA-BD2A-2D14640C6525', '53609BA0-1064-491B-B755-7562C4EEB3FC', '456B16E8-737A-4C1E-8951-CABA44D359DF', '846EE342-7039-11DE-9D20-806E6F6E6963', 'ABB81A2A-BDC5-4F89-827A-E27A0D82A88C', '31A51864-F30F-40D1-8331-10FEFAACA26E', '3D9390CA-7F9D-4BFB-ABD6-606B3564C3CE', '46E22F14-C414-48F8-82EB-D4D5622358B3', '35BF6E1A-628D-4BD4-B5BF-5321069E9CCE']

I don't want to use (used once here to test) uuid module as it can give random 48 bit integer (when it couldn't find the MAC address) which may be some fake MAC address. The problem is when I check the MAC address manually from "Network and Sharing Center" in Control Panel, it shows this :

My questions are :

(i) Why uuid fetched mac address is little bit changed at last?

(ii) The list of netifaces.interfaces() shown here is not similar to the one in the documentation of netifaces like ['lo0', 'gif0', 'stf0', 'en0', 'en1', 'fw0']? Here the fourth address printed by the loop is the right and current MAC address.
The fourth instance of netifaces.ifaddresses(interface) dictionary has an extra key-value pair with key as 2 which is AF_INET (normal Internet addresses). Is it the right process to get the current right MAC address that we check whether this AF_INET is present in the netifaces.ifaddresses(interface) and then get the netifaces.ifaddresses(interface) ?
