I don't think you need these kind of tutorials, the best way to learn programming in general is by having the programming logic. After you have that, everything will be easy for you. I'd recommend you to think for you own of something you would like to get done from scractch, and go piece by piece programming it and searching for functions that would do what you're looking to get done in that part. This method will provide you knownledge, the tutorials are pretty useless in my point of view because the explanation you get in the tutorial is being forgotten in less than an hour, the way to learn is by detecting by yourself why something does what it does.
