I'm going to try to write here about Python practices and design patterns in Python as regularly as I can. (I don't know if I'll be able to do so every week, but I'll try.) As Doug Hellmann wrote to me (about PyMOTW):
I really did start that project as a way to make myself write on a regular basis and to learn...My intentions for this blog are the same.
(BTW, my other blog is at yacitus.blogspot.com.)
