Add support to Python 3.4

[maxxer]

Ubuntu 14.04 (out in few weeks) introduced Python 3.4.
Please add support for this newer version

[g2p]

I did a quick and dirty Travis run and nothing broke, as expected since Python 3.4 has very few incompatible changes. Ubuntu 14.04 has a few changes beyond that (udev always requires testing, and someone posted about a supermin change).

[maxxer]

do you have any plan for supporting ubuntu 14.04? thanks

[mf-lit]

I'd also like to request Python 3.4 support. Thanks.

Just a simple workaround if you need it:
install python3.3
taken from: http://linuxg.net/how-to-install-python-3-3-on-ubuntu-13-04-12-10-and-12-04/
sudo apt-get install python-software-properties
sudo add-apt-repository ppa:fkrull/deadsnakes
sudo apt-get update
sudo apt-get install python3.3

Also in favor of python 3.4 support. Linux Mint 17.3 has Python 3.4, who knows when 3.5 may come out as well.

Hi,
I try to run blocks on Ubuntu 16.04.
I've followed @ozmad instruction to install python3.3. But it seems the pip-3.3 still didn't work. After I ran:
type pip-3.3 || alias pip-3.3='python3.3 -m pip.runner' pip-3.3 --version /usr/bin/python3.3: No module named pip.runner
But I have a working pip3:
pip3 --version pip 8.1.1 from /usr/lib/python3/dist-packages (python 3.5)
Then I tried the blocks installation using pip3:
`
pip3 install --user -r <(wget -O- https://raw.github.com/g2p/blocks/master/requirements.txt)

Does anyone know how to install supermin 4 on Ubuntu 16.04 so I can run blocks?
IMHO blocks is an important companion tool for bcache. Too bad the development is stopped. I've tried the Ubuntu Raring Live CD alternative to install blocks but somehow the live cd just showing the dots progress bar.

[bjmgeek]

Python 3.6 is out now. I'm trying to get blocks to build on it.

[modem7]

do we know if this works with Python 3.5/3.6?
