![]() This is an example of priority queues using a Python sorted list.Ĭode: #Implementing Priority Queues with Sorted list Here are some of the examples of priority queues in Python, which are as follows: Example #1 Priority queues are also used in Process Scheduling, where a high-priority task is assigned to the CPU before a low-priority task. Operating System: It is also used in the OS for load balancing and Interrupt handling.The priority queue keeps track of unexplored routes the one with a lower bound on the total length is the smallest and is given the highest priority. Artificial Intelligence: A* search algorithm finds the shortest path between two vertices of a weighted graph, first trying out the most promising routes.Data Compression: It is used in Huffman codes, which are used to compress data.Graph algorithms: The priority queues are used in graph algorithms like Dijkstra’s Shortest Path and Prim’s Minimum Spanning Trees. ![]() Here, the order is not a matter of interest. ![]() This queue is a bit different from the LIFO and FIFO queues. Print("LIFO Queue Size:", lifo_queue.size()) Here is the example of the LIFO(last in, first out) queue: The same addition and deletion can be done over LIFO as well. # Dequeue (remove) an element from the queue Here is an example of a FIFO queue: addition and deletion of one element in the queue: Types of Queue in Pythonīelow are the different examples as follows: 1. Python provides this in the form of a module called “queue,” which you can import into the Python environment and use directly.
