http://www.pythononline.co.uk/et/tutorial.htm is the best site I know, and I have scanned tons of tutorial sites. It has a lot of newbie friendly stuff. It seems to have 1.4.0 used, but afterall they are quite the same. I personally prefer the newest version of 1.5.0 (26.04.2007), you can found these newest versions from here.
Also you should check the stickies from the forum, and there is millions of stuff you can find by using search. If you can’t find it with search, feel free to ask, there is always somebody to help. I won’t take you as my apprentice, but can give you some help, if you need some, just pm if you like. Note I don’t know everything and will never know, but I am releasing my 4th map, so I know something.
Edit was too slowly typing. Link was given at the time I was writing…
