i think there is another option you aren't thinking about.  you mentioned learning with standard tutorials about basic 
things like concatenating strings.  you also mentioned that you would like to learn by writing one large program, step 
by step.  i think there is a third option you should consider, and IMO it's the best.  it's studying small fully working 
recipes that concentrate on one issue at a time and gives you a good foundation to build upon.  fortunately, there is a 
book that does just this and it's called "Python Cookbook".   i think if you try to go for the one big program, you will 
miss out on a lot of important stuff.  I think there are also free online tutorials that do much the same thing such as 
"Dive into Python".  anyways, just my opinion.
