Where does one go to learn Python Idioms? One of the top referred resources is the Python Cookbook, found in living and book form. Jonathon Gennick has put out an request to submit entries to the Python 2.4 version of the cookbook.
O'Reilly's "Hardcore Java" caught my eye yesterday in looking, but failing to find the Zopista's Plone book in Borders yesterday. Would a similar Python book be useful? Necessary? Perhaps it's smarter to hold out for a Developer's Notebook covering XML or Twisted.
My perspective on advanced Python books is rather narrow, and so is the Python Wiki AdvancedBooks page.
