Default printing behavior for classes

[Ben Glazer]

I'm looking for a way to set default printing behavior for a class I've
defined.  Lists are printed in a certain format by default.  I'd like to
be able to define this for any type of class.  It'd be really nice if
there were something I could include in my class definition, e.g.

	class Board:
	    def __init__(self, width=2, height=4, length=20):
		self.width = width
		self.height = height
		self.length = length

	    def __print__:
		print "[%s,%s,%s]" % (width,height,length)

such that

	b = Board(8,8,2)
	print b

would print "[8,8,2]".

Is there anything in Python that encapsulates this functionality, or
should I resign this desire to a feature req for Python 2.0?


Thanks,
Ben
