![]() Therefore, the item that is inserted first in the queue will be the first item that will be removed from the queue and it satisfies the FIFO methodology. The items that can be inserted from is the rear end and the items that are removed from the queue are from the Front end. A queue has two ends such as the front end and rear end. It is the same in Python and works on the same methodology “First in First Out” (FIFO). What is a Queue in Python?Īs we just discussed what is a queue. Here are going to discuss its implementation in Python Programming Language. A queue can be implemented in programming languages such as Python, Java, C++, etc. It will process the tasks in a manner called “First In First Out” which means the first process or task in the queue will be executed and removed first, after that other processes will be started. Queues are very useful for example, if we need a process to be executed one after other automatically in an order i.e. All these types of queues are used for different scenarios. There are different types of queues like a simple queue, priority queue, circular queue, and deque or double-ended queue. The queue is widely implemented as a waiting list for single shared resources or devices such as Printers, CPU, Disk, etc. Queue follows a specific order for the operations to be performed on the data. How to add more than one element in Python?Ī queue is a type of data structure that holds data in a First in First Out manner. ![]() ![]()
