In recent years I have given courses at my university introduction python(xy). Now I published my manuscript as a paperback as well as an e-book. If you are interested to give such a course, it may be stimulus and model. Others might take this as a hint for potential python(xy)-users. It seems to be the only book dedicated to python(xy), at least, if you search on Amazon's homepage for "python(xy)" only my book is presented. The e-book you may find in Kindle shop.
The title of the book is: "Performing Science with Open Source Software - Utilizing Python(x,y)"
