A Python queue is a data structure that implements the First In, First Out (FIFO) paradigm, basically working like a pipe. You shovel something into the pipe on one side and it falls out on the other side of the pipe.
The main difference between this queue shoveling and shoveling mud into physical pipes is that, in Python queues, things do not get mixed up. You put one unit in, and that unit comes back out on the other side. Next, you place another unit in (say, for example, an instance of a class), and this entire unit will come back out on the other end as one piece. It comes back out at the other end in the exact order we inserted code into the queue.
Queues are containers that hold data being fed into the queue from potentially different data sources...
