Hi,
So I went on the net on the off chance that the info I was looking for
was easy to obtain, and I found out about trial.
I cloned the git and did:
python bin/trial twisted
I got the following:

Is that a trial error or a Twisted test failing?
Sorry if this is a stupid question, but (terrible, I know) I've never
used tests before.
Another quick google told me that Trial was ported to Python3, so I'm
not sure... If it's a test failing, it's not really telling me where the
failure is.
Cheers.

Hi Chris,
Twisted does not yet support Python 3 on Windows.
That's a shame. I've never contributed to an open source project
before, but I'd be glad to try and help out. I feel I __may__ know
enough Python now to certainly have a shot at it.
If you feel like you might, you definitely do :-). Often people feel
like they need to be advanced rocket surgeons to work on Twisted, but
in fact, our robust code-review process means that you don't have to
worry about making mistakes at all. Just submit your best effort, and
you'll get a code review telling you how to improve it so that it can
be integrated (and you _will_ get at least one round of review: I
created Twisted, and even _I_ can't usually land a patch without one
or two rounds of review ;-)).
Thanks for offering to help out! If everybody who wanted Python 3
support just signed on to work on a ticket like this, the port would
have been finished a year ago ;-).
There's a ticket athttps://twistedmatrix.com/trac/ticket/8025#ticket which
makes all the tests pass on the platform; I just need to work on it some more.
I expect Twisted 16.0 to have base support for Python 3 on Windows.
As above, if I can help, please tell me how!
Our toolchain is a little clunky (sorry about that) for hysterical
raisins.
Before I launch into an explanation though, are you already familiar
with Git and/or how to contribute on GitHub?
