Hi all,****
I have a question about reactor of “twisted.internet” module. I found below;****
The default reactor is “select”;****
[root@karadag internet]# pwd****
/usr/lib/python2.6/site-packages/Twisted-10.0.0-py2.6-linux-x86_64.egg/twisted/internet
*[root@karadag internet]# cat reactor.py*

The reactor is the Twisted event loop within Twisted, the loop which drives
applications using Twisted. The reactor provides APIs for networking,****
threading, dispatching events, and more.****
The default reactor is based on C{select(2)} and will be installed if this
module is imported without another reactor being explicitly installed.****
Regardless of which reactor is installed, importing this module is the correct****
way to get a reference to it.****
New application code should prefer to pass and accept the reactor as a****
parameter where it is needed, rather than relying on being able to import this****
module to get a reference. This simplifies unit testing and may make it easier****
to one day support multiple reactors (as a performance enhancement), though
this is not currently possible.****
