python priority queue library

A priority queue is a data structure that maintains a set of elements, each associated with a priority. The basic idea is that the element with the highest (or lowest) priority can be efficiently retrieved, removed, and updated. Python's queue module provides an implementation of a priority queue through the PriorityQueue class.
The PriorityQueue class in Python's queue module is a part of the standard library and provides an efficient implementation of a priority queue. It uses a heap data structure to manage elements based on their priorities.
In this example, tasks are tuples where the first element is the priority and the second element is the task description. The tasks will be retrieved from the priority queue in ascending order of priority.
You can customize the priority queue to handle custom objects by defining a comparison method for the elements. By default, elements are compared using the less-than operator (), but you can override this behavior.
In this example, the CustomObject class has a custom comparison method (__lt__) to define the ordering based on priority.
The PriorityQueue class in the queue module is a powerful tool for managing elements with priorities. It is especially useful in scenarios where tasks or elements need to be processed in a specific order. Customize it according to your needs and leverage its efficiency for handling priority-based data structures in your Python projects.
