Queue:



Queue is also not a built-in data structures in python. The queue is a user-defined data structure in python that is used to store data in the First In First Out (FIFO) manner. In queues, the insertion and deletion are done at different ends, where the insertion is done at the rear end and the deletion is done at the front end. So, the data which is inserted first will be removed from the queue first. Since the first element inserted is served and removed first, the queue data structures in python are also known as the First Come First Served data structure. The most common associated method of queues are enqueue(), dequeue(), front(), rear(), empty() etc.
