I'll create my own Queue object first, and next I will enqueue an item into it. Producer -> Queue -> Consuming: Work Queue used to distribute time-consuming. I'll start up the Python interpreter here, and we can try this out. As with other Python tutorials, we will use the Pika RabbitMQ client version 1.0.0. And we talked about how the reason we do that is because we want to sort of save the end of the list for popping and use the front of the list for inserting. The enqueue is an operation in a queue data structure that adds an element to the rear or tail of the queue.
Now we know that we're going to be operating on our empty list, which is called items, but instead of appending the item to the end of the list, like we did for a stack, we want to now insert the item into the zeroth index of the list. Various operations can be performed on a Queue in Python, such as adding elements to the back of the queue, removing elements from the front of the queue, and checking the size of the queue. For implementation, we will define a queue class which will have a list to contain the elements and a queueLength field to contain the length of the list.

Again, as we talked about, we have to pass in as a parameter the item that we want to add into the queue, and in the body of our method, we're going to need to do something with that. How to implement queue in python Queue is a linear data structure in which we can only access or remove the element which was added first to it. Let's start coding the minimal functionality we need for our Queue class.
