no way to delete/hide a single pynguin?

[GoogleCodeExporter]

I can't seem to find a way to delete a single pynguin.

I can delete the reference to it, which is OK in combination with moving it 
offscreen, but I'd like to be able to do stuff like p.hide(), p.remove(), or 
q.remove_everything_else()

What version of the product are you using? On what operating system?
HEAD, Ubuntu 9.10

I am adding a pynguin.remove() method. It works like this:

    def remove(self, pyn=None):
        '''take the given pynguin (or this one if none specified)
            out of the scene.

        If removing a different pynguin from this one, this one will
            adopt all of the drawn items from the other pynguin. In
            other words, items drawn by the pynguin that is being
            removed will not be cleared immediately, but can later
            be cleared by this pynguin.

        If this pynguin is removing itself, it will first clear all
            of its own drawings, otherwise there will be no way to
            clear them out later.
        '''

Give it a try to see if it does what you need.

See also p.reap() for removing all other pynguins and taking charge of their 
drawings all at once.

Any chance we could have an argument for .remove that lets you choose whether 
to remove a penguin's drawings?  e.g. if you want to remove a penguin but leave 
its drawings, is that easy?  Or do drawings need to be owned by a penguin?   If 
so, maybe there could be an invisible/omnipresent penguin?

Well...

You can certainly create an invisible, omnipresent pynguin to hold any drawings 
by pynguins that you want to get rid of:

>>> reaper = Pynguin()
>>> reaper.avatar('hidden')

Now make some drawings

>>> circle(100)
>>> square(150)

Use the reaper to get rid of the pynguin

>>> reaper.remove(p)

Need a new pynguin to draw with?

>>> promote(Pynguin())
>>> lt(45)
>>> fd(100)
>>> reaper.remove(p)

Remember that if you have a bunch of other pynguins drawing, and want to get 
rid of them all at once -- but keep their drawings -- use the reap() method:

>>> for i in range(20):
>>>    pyn = Pynguin()
>>>    pyn.right(10*i)
>>>    pyn.fd(100)
>>>
>>> reaper.reap()
