Originially I had it written as 

class foo:
	def __init__():
		self.frog = list[0]
		#...and so on...

(I guess this question would also be for Jay, who also was kind enough to
 answer) but, er, whats the difference between a Class attribute and an
instance attribute? is this like the java 'static final' idiom?
