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.
