PriorityQueue is a type of queue that comes with priorities, and its usage is as follows:<\/p>\n

    \n
  1. Import the PriorityQueue class: First, you need to import the PriorityQueue class by using the following statement:<\/li>\n
  2. import the PriorityQueue class from the module queue<\/li>\n
  3. Instantiate a PriorityQueue object: Create a PriorityQueue object using the PriorityQueue class.<\/li>\n
  4. Create a priority queue with the variable name pq.<\/li>\n
  5. Adding elements: Use the put() method to add elements to the PriorityQueue, where the priority of the elements can be any type of value, such as integers, float numbers, strings, etc.<\/li>\n
  6. Insert the numbers 3, 1, and 5 to the priority queue.<\/li>\n
  7. Accessing elements: By using the get() method to retrieve elements from a PriorityQueue, the highest priority element will be returned.<\/li>\n
  8. retrieve an element using pq.<\/li>\n
  9. Check if the PriorityQueue is empty: Using the empty() method, determine if the PriorityQueue is empty. If it is empty, return True; otherwise, return False.<\/li>\n
  10. if the priority queue is empty, print “PriorityQueue is empty”<\/li>\n
  11. To get the size of the PriorityQueue: use the qsize() method to get the number of elements in the PriorityQueue.<\/li>\n
  12. The size is equal to the queue’s current size.<\/li>\n<\/ol>\n

    It is important to note that PriorityQueue is a thread-safe queue, suitable for use in a multi-threaded environment. To use it in a multi-threaded environment, you can import the thread-safe PriorityQueue class with the following statement.<\/p>\n

    from queue import PriorityQueue as ThreadSafePriorityQueue\r\n<\/code><\/pre>\n","protected":false},"excerpt":{"rendered":"
