No, I just saw too much stuff which pretends to teach something, but
instead promotes an operating system. Contrary to many people I do
not believe that something is automatically better when it runs
under windows and when 'win' is part of the name.

IMHO a beginner needs to use an editor and an interpreter or
compiler. How to copy and remove files and directories is helpful
also.

I did not consider to teach programming without tools and without
using files. The common denominator for file systems is IMHO enough
to teach programming to beginners. Do you consider access control
lists, mount points and symbolic links essential for the programs
taught after 'hello world'?

You obviously think that unportable programming is needed to
motivate people. This is IMHO far from true. There are many portable
programs which are motivational. I cannot provide portable Python
examples but examples of portable Seed7 programs can be found here:

I can think of several reasons why some people would not see it this
way.

Maybe you take the opportunity and look at it now. :-)
