Windows 7 does not have a MAC address. It is an operating system.

Ethernet adapters have MAC addresses. Your computer will have one or 
more Ethernet adapter.
 From a command prompt enter
ipconfig /all

You will see something like (this is from MY computer, Windows 2008 
Server, similar to Win 7):

    DNS Servers . . . . . . . . . . . : fec0:0:0:ffff::1%1
                                        fec0:0:0:ffff::2%1
                                        fec0:0:0:ffff::3%1
    NetBIOS over Tcpip. . . . . . . . : Enabled

etc.

Each Ethernet adapter has a Physical Address (MAC Address).

When you run ipconfig /all - if you see only one Physical Address, then 
that is the one you want.

If you see more than one then you must decide which Ethernet adapter you 
want.

Then you use Popen (in subprocess module) to run ipconfig /all, capture 
the output and parse it for the desired Ethernet adapter, then parse 
that section for the Physical Address.

There may be another (better?, easier?) way but this will work.
