Microsoft Visual C++ Compiler for Python 3.4

I know that there is a “Microsoft Visual C++ Compiler for Python 2.7” but is there, currently or planned, a Microsoft Visual C++ Compiler for Python 3.4 or eve Microsoft Visual C++ Compiler for Python 3.x for that matter?

A layman’s explanation for “Everything is a file” — what differs from Windows?

I know that “Everything is a file” means that even devices have their filename and path in Unix and Unix-like systems, and that this allows for common tools to be used on a variety of resources regardless of their nature. But I can’t contrast that to Windows, the only other OS I have worked with. I have read some articles about the concept, but I think they are somewhat uneasy to grasp for non-developers. A layman’s explanation is what people need!
