How to use python ordered queue

In python, you can use the Queue class in the queue module to implement ordered queue operations. The Queue class is a threadsafe queue that provides a series of methods to operate the queue.

The following is a sample code using an ordered queue:

from queue import Queue

# 创建一个有序队列
q = Queue()

# 向队列中添加元素
q.put(1)
q.put(2)
q.put(3)

# 从队列中获取元素
print(q.get())# 输出：1

# 判断队列是否为空
print(q.empty())# 输出：False

# 获取队列的大小
print(q.qsize())# 输出：2

# 清空队列
q.queue.clear()

In the above example, we first imported the Queue class and created an ordered queue q. Then use the put() method to add elements to the queue, and use the get() method to get elements from the queue. We also use the empty() method to determine whether the queue is empty, the qsize() method to get the size of the queue, and the clear() method to clear the queue.

It should be noted that the Queue class is thread-safe and suitable for queue operations in a multi-threaded environment. If you only use queues in a single-threaded environment, consider using deque or list to implement ordered queue operations.
