Were it more serious code, it would be implemented as a class but it should be enough to illustrate the workings: import random

Swinsian vs enqueue code#

That diagram shows a queue where you've enqueued the numbers 1, 2 and 3 in that order, without yet dequeuing any.Д«y way of example, here's some Python code that shows a simplistic queue in action, with enqueue and dequeue functions.

There are variations of queues such as double-ended ones where you can enqueue and dequeue at either end but the vast majority would be the simpler form: +-+-+-+ You enqueue items at one end and dequeue at the other, just like a line of people queuing up for tickets to the latest Taylor Swift concert (I was originally going to say Billy Joel but that would date me severely). You could check it out for reference.Д®nqueue and Dequeue tend to be operations on a queue, a data structure that does exactly what it sounds like it does. This is quite similar to push and pop in a stack, but the terms enqueue and dequeue avoid confusion as to whether the data structure in use is a stack or a queue.Д¬lass coders has a simple program to demonstrate the enqueue and dequeue process. Similarly, a queue data structure follows a 'First In First Out' policy (as in the case of a normal queue when we stand in line at the counter), where the first element is pushed into the queue or 'Enqueued' and the same element when it has to be removed from the queue is 'Dequeued'. The stack data structure follows the 'First In Last Out' policy (FILO) where the first element inserted or 'pushed' into a stack is the last element that is removed or 'popped' from the stack. Some of the basic data structures in programming languages such as C and C++ are stacks and queues.
