Plus 1 for Code Academy. The 13 Lessons are broken down into sub lessons
so there are between 22 and 24 total lessons/exercises that must be
completed to move on with the course. You learn by doing which is the only
way to really learn programing. The thing about Code Academy is that it is
entirely free, there are no adds and if you get stuck at any point you can
ask a question and get a response as well as see the questions from
others. Your course work is saved so you can go back and review your work
at any time. I'm not knocking other courses, books etc. I have several
python books. But Code academy takes a beginner with no programing and by
the last Lesson set you will be using Python to build classes in object
oriented programing. It may not be as exhaustive as other courses but you
will have a good feel for the basics of the language.
It doesn't cost you anything to try it out and even if it isn't as in depth
as other courses I would argue for a beginner it is very well balanced
giving you the general concepts of all programing languages as applied to
python. If you feel you need more, than at least you have a solid base in
the language that cost you just your own time.
