How do I add two integers together with Twisted?
I have two integers in my program; let's call them "a
" and "b
". I would like to add them together and get another integer as a result. These are regular Python int
objects. I'm wondering; how do I add them together with Twisted? Is there a special performAsynchronousAddition
function somewhere? Do I need a Deferred
? What about the reactor? Is the reactor involved?
Solution 1:
OK, to be clear.
Twisted doesn't do anything about cpu bound tasks and for good reason. there's no way to make a compute bound job go any quicker by reordering subtasks; the only thing you could possibly do is add more compute resources; and even that wouldn't work out in python because of a subtlety of its implementation.
Twisted offers special semantics and event loop handling in case the program would become "stuck" waiting for something outside if its control; most normally a process running on another machine and communicating with your twisted process over a network connection. Since you would be waiting anyways, twisted gives you a mechanism to get more things done in the meantime. That is to say, twisted provides concurrency for I/O Bound tasks
tl;dr: twisted is for network code. Everything else is just normal python.
Solution 2:
How about this:
c = a + b
That should work, and it doesn't need to be done asynchronously (it's pretty fast).
