I just read this book and liked it. Here is a review: Sometimes a picture is worth a thousand words. "Beginning Python Visualization: Creating Visual Transformation Scripts", published in February 2009 by Apress, shows how Python and its related tools can be used to easily and effectively turn raw

Is there a better way to chose a slice of a list?

Re: Get multiprocessing.Queue to do priorities

The Queue module, apparently, is thread safe, but *not* process safe. If you try to use an ordinary Queue, it appears inaccessible to the worker process. (Which, after all, is quite logical, since methods for moving items between the threads of the same process are quite different from inter-pr
