Python 3.4 support?

[ianozsvald]

Hello, thanks for the library. This might be the tool that helps me stop showing other data scientists how to write new Flask(+swagger) apps from a template.

I'm a Python 3.4 developer (I'll also note #4), I can't get pyxley running. Firstly - maybe you could mark in the README that only Python 2.7 is supported at present?

I tried running 2to3 --write pyxley/ after a git-clone and it said it succeeded (so all the files might now be Python 3.4 compatible). I then ran python setup.py install which also succeeded. Oddly I had to run pip install pyreact by hand, I'm not sure if there's a problem with the conversion process.

I started to follow the guide here http://multithreaded.stitchfix.com/blog/2015/07/16/pyxley/ but the first imports fail (from pyxley.utils import FilterFrame - no .utils?). I then tried running the included examples but had errors due to the 2to3 conversion and str datatypes e.g.

pyxley/examples/datamaps/project $ python app.py

Traceback (most recent call last):
  File "app.py", line 55, in <module>
    sb = ui.render_layout(app, "./static/layout.js")
  File "/home/ian/anaconda/envs/scratch/lib/python3.4/site-packages/pyxley/ui.py", line 90, in render_layout
    static_path=path)
  File "/home/ian/anaconda/envs/scratch/lib/python3.4/site-packages/pyxley/react_template.py", line 64, in __init__
    self.to_js()
  File "/home/ian/anaconda/envs/scratch/lib/python3.4/site-packages/pyxley/react_template.py", line 25, in to_js
    self.write_to_file(js)
  File "/home/ian/anaconda/envs/scratch/lib/python3.4/site-packages/pyxley/react_template.py", line 17, in write_to_file
    f.write(s)
TypeError: 'str' does not support the buffer interface

The above error occurs for datamaps, metricsgraphics, datatables.

I'll try using Python 2.7 at some point.

+1 to noting in README that only python 2.7 is supported currently

I haven't had a chance to look at 3.4 yet, but thanks for looking in to this. In the meantime, I'll definitely add to the readme that only python 2.7 is currently supported.

I got it working in python 3.4, there were some string/binary issues in the writing of layout.js. I'll try to push a fix soon.

@ianozsvald Should be 3.4 compatible now. Also, I'll edit the blog to remove the FilterFrame bit. It was removed, but I didn't catch it in the blog.

@nmkridler Hi Nick - just to say "thanks" for fixing this, Python 3.4+ compatibility is much appreciated :-)
