# Enqueue or dequeue a bit, with latter having probability of 10%. Return (itm, lst) # Then return item and new list. Lst = lst # Change list to remove first item. Return lst # And return list (for consistency with dequeue). Lst.append(itm) # Just add item to end of list. Were it more serious code, it would be implemented as a class but it should be enough to illustrate the workings: import random Synonyms for QUEUE: line, line up, cue, file, sequence, align, place, prioritize Antonyms of QUEUE: disarray, mess (up), disorder, disarrange, muss (up), derange.

QUEUE DEFINITION CODE
That diagram shows a queue where you've enqueued the numbers 1, 2 and 3 in that order, without yet dequeuing any.īy way of example, here's some Python code that shows a simplistic queue in action, with enqueue and dequeue functions. In queue refers to a physical line of people or cars in British English. 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). Enqueue and Dequeue tend to be operations on a queue, a data structure that does exactly what it sounds like it does.
