<p><sup>*</sup> Exactly when Python calls the <code>__del__()</code> special method is incredibly complicated. To fully understand it, you need to know how <a href=http://www.python.org/doc/3.1/reference/datamodel.html#objects-values-and-types>Python keeps track of objects in memory</a>. Here&#8217;s a good article on <a href=http://www.electricmonk.nl/log/2008/07/07/python-destructor-and-garbage-collection-notes/>Python garbage collection and how it relates to class destructor methods</a>. You should also read about <a href=http://mindtrove.info/articles/python-weak-references/>weak references</a>, the <a href=http://docs.python.org/3.1/library/weakref.html><code>weakref</code> module</a>, and probably the <a href=http://www.python.org/doc/3.1/library/gc.html><code>gc</code> module</a> for good measure.
