[Tutor] how to determine windows version

[Todong Ma]

You can use either sys.getwindowsversion() or platform.platform() function.

platform.platform() gives a more friendly string, e.g. 
"Windows-7-6.1.7600", that means Windows 7 with major version 6, minor 
version 1 and Build No. 7600. While sys.getwindowsversion() will return 
a named tuple, like (major=6, minor=1, build=7600)
