Extending Classes in Python

I tested today, and found that you can actually extend a class, on itself. Not just by using setattr(), but also by creating a new class:

>>> class bar:
...  def monkey(self):
...   print 'neat'
...
>>> class bar(bar):
...  def horse(self):
...   print 'sweet'
...
>>> bar().monkey()
neat
>>> bar().horse()
sweet

Again, this might be in the manual, I just didn’t know of it until some ten minutes ago.

This is Simply Jonathan, a blog written by Jonathan Holst. It's mostly about technical topics (and mainly the Web at that), but an occasional post on clothing, sports, and general personal life topics can be found.
