It is very easy to work with queue in python. Last in First out Queue: Over here, the element that is entered last will be the first to come out.To work with LIFO, you have to call LifoQueue() class from the queue module.First in First out Queue: For this, the element that goes first will be the first to come out.To work with FIFO, you have to call Queue() class from queue module.There are mainly two types of queue in Python: The items in queue will be removed in the order they are inserted. You just cannot remove the item 5 randomly from the queue, to do that you will have to remove all the items before 5. In a queue, the items are removed in order and cannot be removed from in between. Hence the queue is called FIRST IN FIRST OUT (FIFO) Item 1 was the first one to be inserted in the queue, and while removing it is the first one to come out. If you remove an item from the queue, the first element you will get is 1, as shown in the figure. The Front represents the point where the items from the queue will be removed. The Rear represents the point where the items are inserted inside the queue. Here is a diagrammatic representation of queue: The same logic goes for the queue data structure too. The queue can be easily compared with the real-world example the line of people waiting in a queue at the ticket counter, the person standing first will get the ticket first, followed by the next person and so on. Methods available inside Queue and LifoQueue class.The items are entered from the rear and removed from the front side. ![]() The data that is entered first will be removed first, and hence a queue is also called “First in First Out” (FIFO).
