Re: fifo queue

Unless the queue is really large, just use the pop operation to get stuff off the top of the queue. That causes O(n) operations but it should be fast if n is small. class queue(list): push = append def pop(self): return list.pop(self,0) should do about what you wr

persistent fifo queue class

I'm looking to see if there are any examples or prewritting fifo queue classes. I know this is a broad topic. I'm looking to implement a simple application where a web server enqueue and pickle using a local socket on to a 'queue server' -- and then I will have another app
