This is a great resource and just the right timing since I'm planning on building a website on Google App Engine using Python with Flask.
As I mentioned, I'm 30 pages into LPTHW, but I think I will be switching immediately to Real Python, since it looks a lot more practical for my needs.
Thanks again to the people who built that site, to the person who submitted it on HN and to all the people who voted on it, so it gets to first page! You all rock!
