That's right, the names ‘_’ and ‘__’ have no special meaning in Python-the-language so they don't appear in the index. Steven and I both used those respective names to communicate “never going to use this value but the syntax requires a name here”. > where might I find written discussion of these? I find Nick Coghlan's answer on StackOverflow <URL:https://stackoverflow.com/questions/5893163/what-is-the-purpose-of-the-single-underscore-variable-in-python/5893946#5893946> to be especially helpful. Nick also explains that, because the name ‘_’ has too many conventional meanings already, the name ‘__’ is better for “don't need this value but I am required to specify a name”. -- \ “The double standard that exempts religious activities from | `\ almost all standards of accountability should be dismantled | _o__) once and for all.” —Daniel Dennett, 2010-01-12 | Ben Finney -- https://mail.python.org/mailman/listinfo/python-list
