Update for Python 3

[vsoch]

Hey @rwblair - I started to update the expfactory-docker image (django needs a version update) and realized we need expfactory with python 3. I think one of the contributors started working on this back in 2016 and said he would PR, but never got around to it. What I've done here is (most of the work I think?) to fix up print statements, etc.

And I'm just realizing now that the circle ci needs updating too (still version 1!) I'll start working on that, and test for Python 2 and 3.

@vsoch nice, this will be useful for sure. I'm working on upgrading expfactory-docker to use boto3 where necessary since the api that boto 2 uses is being deprecated. Was going to start in on the python 3 and django 2+ upgrade some time later this year.

I also need to upgrade the entire cognitve atlas site as well before new years which might be an undertaking since it will involve a major neo4j upgrade. Fortunately the cognitveatlas python api library shouldn't be too terrible to get going in python 3.

[vsoch]

I can help with both! :) I'm working on a new circle recipe for testing now.

oup, just hit a python 2 bug in expfactory as a result of cognitive atlas - going to update that first!

@rwblair the testing is set up and working, I'd like to propose leaving this open while work on expfactory-docker is done - I'll install from this branch (and update to it) if I hit any issues with the updates.

[vsoch]

good news! I just got expfactory-docker running, and instead of printing issues with cogat or expfactory due to python versions, it's all just updating the code in expfactory-docker (woohoo!) So it should be pretty easy to update everything for Python 3 - I haven't run yet today and it's almost 7pm so I'm going to do that and pick up on this likely tomorrow. Solid work today @rwblair !

hey @rwblair I'm done with these early fixes, let me know when you want to discuss! Have an eggcellent Friday!

[vsoch]

@rwblair I'm about to push (version 2) update for expfactory, so it's good time to test pushing this version first.

[vsoch]

Ah this is very cool! We can push version 1 expfactory to pypi, and it fits right in nicely to where it should be! See the release for python 3 here https://pypi.org/project/expfactory/2.5.47/

[rwblair]

@vsoch Nice! I'll be sure to test it out when I get a chance, and pin requirements.txt accordingly

[vsoch]

Sweet! Let me know if anything is amiss and I'll get on it asap.

Holy crap, I added complete automated builds to expfactory this morning, and hit one of those "omg why didn't I specify a version" moments for psycog2. It took me like 4-5 hours to get it right! expfactory/expfactory#120
