Why are you doing it at the low level? Have you consideren using a framework
like Django for example?
Who is this question addressed to? Me?
If so, my answer is that Django is an awfully large dependency if all
you need is a queue.
But if you think that Django has a good solution to the problem, by all
means show us how you would use it.
P.S. we prefer that you don't top-post on this mailing list. It makes it
easier to understand replies if they follow what they are replying to,
rather than come before.

Hi I am new to python and was wondering what the best way to create an
order(bid and offer) queue, then match a bid and offer so that if
bid==offer, creates a filled order FIFO in python cgi using mysql? Does
anybody have any ideas? It would be greatly appreciated.
The simplest way to use a queue is with a list:
queue = []
You push items onto the queue with queue.append(item) and pop them off with
queue.pop(0).
However, popping items may be slow if the queue grows very large (tens of
thousands of items). It might be better to use a deque (double ended queue)
instead of a list:
from collections import deque
queue = deque()
To push items onto the right hand side of the queue, then pop them off the
left hand side:
queue.append(item)
queue.popleft()
As for the rest of your question, I don't understand what you mean by an
order(bid and offer) queue. Perhaps you could give an example of what you
mean.
