Using XML for configuration is a good example of a worst practice, but using Python instead isn't best practice. There are good arguments that a configuration language shouldn't be Turing-complete. See for instance this blog post: http://taint.org/2011/02/18/001527a.html The problem with XML is just that it's not very human-readable; it doesn't need all the extra power of Python. This may be something that's hard to appreciate until you've actually experienced an outage because somebody checked in a configuration change that parsed and passed tests but nonetheless was invalid due to configuration that couldn't be evaluated until runtime. A better choice for configuration would be something that is both easily readable and *simple* such as JSON or YAML, or an appropriate DSL. -- https://mail.python.org/mailman/listinfo/python-list
