Req. for comments section "Basic Data" in intro book

[Alf P. Steinbach]

I added a section on "basic data" to ch 2 of my writings, an introduction to 
programming (with Python as main language).

The intended reader is someone who is intelligent and wants to learn programming 
but knows little or nothing about it.

As before it would be nice with feedback on this.

list of references. :-)
