Python has a built-in module called `queue` which provides classes for implementing queues. The `Queue` class is one of the main classes provided by this module and it is used to implement threadsafe FIFO (First-In-First-Out) data structures.
This example creates a queue object called `q` and adds three integers to it using the `put()` method. The `queue` attribute of the queue object is then printed, which will output a list of the items in the queue: `[1, 2, 3]`.
2. Removing items from a queue:
import queue
q = queue.Queue()
q.put(1)
q.put(2)
q.put(3)
while not q.empty():
print(q.get())
This example creates a queue object called `q` and adds three integers to it using the `put()` method. Then, a while loop is used to remove items from the queue using the `get()` method until the queue is empty. The output of this code will be:
1
2
3
The package library for this module is `queue`.
