I don't use Blender myself, so this will be a more generic, high-level
answer...

This definition specifies that label() takes two mandatory parameters - text
and position - and one optional parameter, orientation. What makes
"orientation" optional is the fact that a default value is supplied:
"orientation='z'". In other words, "orientation" is equal to "z" unless you
specify otherwise in your call to label().
Take a look at this section of the Python docs:
http://docs.python.org/tutorial/controlflow.html#more-on-defining-functions
Hope that helps...

[Tutor] Difficulty Understanding Example Code for Blender Script
This code was part of a Blender script to build a 3d bar graph, so I don't
know if understanding Blender is a prereq for understanding this code. The
function is for the axis labels.
def label(text,position,orientation='z'):
txt=Text3d.New('label')
txt.setText(text)
ob=Scene.GetCurrent().objects.new(txt)
ob.setLocation(*position)
if orientation=='x':
ob.setEuler(-pi/2.0,0,0)
elif orientation=='z':
ob.setEuler(0,0,pi/2.0)
print 'label %s at %s along %s' %(text,position,orientation)
I understand it for the most part except for the orientation part. I assume
orientation is for the 3d text object, but how is it determined whether it
is x or z? Please keep replies simple; I am a newcomer to programming (and
if this makes no sense at all, I would appreciate polite inquiries for more
info).
Using Blender 2.49b and Python 2.6
Thanks a bunch,

[Tutor] Observer design pattern: request for feedback
Hi, I decided I wanted to use the Observer design pattern in my application. I did a little googling, but all the examples that I found of Observer in Python seemed over-complicated, so I wrote my own simple version. It doesn't have as many features as other Observer implementations might, but it's a start. Any critical comments or suggestions would be greatly appreciated.
