python3 support

[Bekt]

The library doesn't seem to work with python3. A lot of people have moved away from python2, so it'd be nice to add support for python3 to take advantage of the library.

Python 3.5.1 (default, Dec 26 2015, 18:11:22)
[GCC 4.2.1 Compatible Apple LLVM 7.0.2 (clang-700.1.81)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

>>> import dockercloud
>>>
>>> dockercloud.Action.list()

TypeError: Cannot mix str and non-str arguments

I've tested the same code with python 2.7.10, and it works just fine.

Same experience for me, I put it in a forum post. Issue occurs with environment variables as well as with setting the relevant attributes.

Any fix or work around for this?

[Midnighter]

There are some open pull requests that look promising...

@Midnighter Also added a PR now as well #29. Tests pass in both Python2 and 3. Will see if it gets accepted. Tried to rebase my commits so it looked a little cleaner but could not it seems.

Any update about this issue? Please let me know how I could help to accelerate any advancement toward a solution.

I second this! PR #29 seems good.

My suggested workaround for the impatient:

pip3 install git+https://github.com/penkin/python-dockercloud

This will install the py3-compatible version.
