I had a similar problem when i was using asynchat.fifo, it had a list in the past now it has a deque. So in order to put something to zeroth location (to be compatible with python 2.3 and python 2.4) I did something like:
class fifo(asynchat.fifo):
def __init__(self, list=None):
asynchat.fifo.__init__(self, list)
self.have_deque = hasattr(self.list, 'appendleft')
def push_front(self, object):
if self.have_deque:
self.list.appendleft(object)
else:
self.list.insert(0, object)

q.queue used to be a list, and now it is something else?
I was using bisect module to implement min priority queue, as described
in python library reference (see
http://www.python.org/doc/2.3.5/lib/bisect-example.html). I have found
out that in Python 2.4 q.queue does not support "insert" anymore, which
breaks bisect. Please help!
Thank you,
