Since nobody else mentioned this...
Python classes have a magic method called __del__ which is usually
called just before an object is garbage-collected. Further, Python
uses reference-counting to tell when an object is no longer
accessible. This means that if your resource classes define __del__

Hello!
I have been thinking about how write exception safe constructors in
Python. By exception safe I mean a constructor that does not leak
