In this tutorial we are going to look at the
queue data structure. We’ll take
a look at how this data structure can be used for various tasks and the various
sort of things you can do with queues.
queue data structure is typically used in scenarios where you want things
to be processed in the same order that they were inputted into a system.
For example, imagine you had a system that dealt with user registrations to your
site. You could enqueue any new requests from users to register to your site
queue. Worker threads within your application would then monitor this
queue and process new registrations as they come in.
>>> import queue >>> my_q = queue.Queue() >>> my_q.put('first') >>> my_q.put('second') >>> my_q.put('third') >>> my_q.get() 'first' >>> my_q.get() 'second' >>> my_q.get() 'third'
