Data persistence modules save Python data between program runs. These tools range from simple file-based storage to complex serialization systems, offering different tradeoffs between speed, compatibility, and human readability.

Given below are the different ways to implement a queue in python: list collections.deque queue.Queue Implementation using list The list is a built-in data structure in python that can be used as a queue. In place of enqueue() and dequeue(), there are append() and pop() functions. ...
The following Python program uses theheapqmodule to implement a simple priority queue: importheapqclassPriorityQueue:def__init__(self):self._queue=[]self._index=0defpush(self,item,priority):heapq.heappush(self._queue,(-priority,self._index,item))self._index+=1defpop(self):returnheapq.heappo...
To connect to Azure Cosmos DB, first create an account, database, and container. Then you can connect your function code to Azure Cosmos DB using trigger and bindings, like this example. To implement more complex app logic, you can also use the Python library for Cosmos DB. An asynchronous...
