In another email you were talking about Python in Drupal. The problem as I and others pointed out is that there is no Python in Drupal. This can also be verified by the lack of a Python requirement on the requirements page on drupal.org:

http://drupal.org/requirements

It sounds like the project you took over did some serious hacking on Drupal, which means that the problems you face won't really be answered by books or courses.

Sadly what you are running into is a very common situation. Over my 10 years of working with Drupal I have taken over projects that people tried to incorporate different server side languages into.

Most online courses now focus on Drupal 7, since Drupal 6 is approaching end of life. There are some pretty significant changes between the two versions, so that might not be of too much help.

Here are some resources though to help you out:

http://drupalize.me/ (very good collection!)

http://drupal.org/books?availability%5B%5D=38414&version%5B%5D=102 (books for Drupal 6)

But the best way to learn it is to just dive in. Set you up a fresh install of Drupal and start playing around with it, adding modules, etc. Once you figure out the basics, then play around with writing some custom modules.

Hope this helps!

Hi All,

I took over a project which involves LAMP, Drupal6 and Python. So far I've done programming mostly in PHP or Python without understanding exactly how Drupal works. Everything was going OK but now the application is behaving very weird, there are some system changes that I'm sure I didn't do (at least directly) and no one else. So at this point I really need to understand how Drupal works (high level). I got books from library but honestly Drupal seems too complicated to me. Is there any source I can use to learn Drupal mostly at system level? I will pay.

Best, Katy
