It'd be helpful if you supplied the code in question.  Then again, we
wouldn't be able to let our imagination wander with what puff might
mean.  <wink>

Anyway, is this the sort of thing you're talking about?

#!/usr/bin/env python

class Foo:

    def __init__(self):
        self.bar = []

    def __str__(self):
        return '<Foo><bar>%s</bar></Foo>' % (str(self.bar),)

l = range(10)

foo = Foo()
foo.bar.append(l)
del foo.bar[0]
print 'foo = %s' % (str(foo),)
print 'l = %s' % (l,)

Cheers,
