The enqueue and dequeue methods use modulo arithmetic to implement the circular behavior of the queue. display prints the items in the queue from front to rear.peek returns the item at the front of the queue without removing it.dequeue removes an item from the front of the queue.enqueue adds an item to the rear of the queue.is_full returns a boolean value indicating if the queue is full or not. is_empty returns a boolean value indicating if the queue is empty or not.The class has several methods to perform various operations on the queue: In the above example, define a CircularQueue class that takes a capacity parameter in its constructor. # Try to add another item to the queue (should print "Queue is full") # Create a circular queue with capacity 3 #Following is an example of how to use the CircularQueue class: Self.rear = (self.rear + 1) % self.capacity Return (self.rear + 1) % self.capacity = ont To create a simple queue, you can use the Queue class from the Queue module. This module provides a simple and efficient way to manage work items. This means that the first item added to the queue will be the first one to be removed. The Queue module in Python provides a FIFO implementation of the queue data structure. Following are some of the most common types: Queue: There are several different types of queues that you can use depending on your use case. This makes queues a powerful tool for building concurrent and parallel applications in Python. Python queues are designed to be thread-safe, meaning that they can be accessed and modified by multiple threads or processes simultaneously without causing errors or inconsistencies in the data. One of the main benefits of using a Python queue is that it provides a simple and efficient way to manage a large number of elements in a thread-safe manner. Queues can also be used for implementing data pipelines and for coordinating communication between different parts of a system. Python queues are commonly used in applications that involve processing large amounts of data or tasks in parallel, where each task or data item is added to a queue, and a set of worker threads or processes are responsible for removing items from the queue and processing them. A Python queue can be thought of as a container that holds a sequence of items, much like a stack or a list, but with a different set of operations. In other words, the elements that are added first to the queue are the first ones to be removed. Python QueueĪ Python queue is a data structure that is used to store and manage a collection of elements in a first-in, first-out (FIFO) manner. Finally, check if the queue is empty again using the empty method. Next, remove the elements from the queue using the get method and print them to the console. Check if the queue is empty using the empty method and print the size of the queue using the qsize method. Then add three elements to the queue using the put method. In the above example, first create an empty queue using the Queue class from the queue module.
