Python3 - SafeConfigParser renamed to ConfigParser

[craigey]

Hi,
I'm not well versed in the world of Python, so please forgive me if the below is nonsense or not anything you can help with:
I'm getting the following error when trying to run / setup kodi-alexa on my self-hosted Apache web server.

[Wed Nov 29 22:52:17.553193 2017] [wsgi:error] [pid 9684:tid 1136] [client ::1:56613] mod_wsgi (pid=9684): Exception occurred processing WSGI script 'C:/Apache24/wsgi-scripts/kodi-alexa/alexa.wsgi'.

From what I can see it's due to me running python 3+ rather than 2.7 as the SafeConfigParser was renamed to ConfigParser. I've tried getting my mod_wsgi to play nicely with python 2.7 & various versions of Apache, but I can't seem to find any other combination that works. Would it be possible to support Python 2 & 3? I've googled & apparently using the module "six" and a try catch block like below might work to support both versions - I'm not sure though.

Taken from:
https://stackoverflow.com/questions/14087598/python-3-importerror-no-module-named-configparser

try:
import configparser
except:
from six.moves import configparser

Is this feasible?

I think there might be some other things we need to do to make it work in Python 3 (not sure if all of the libraries work the same or have compatible upgrades), but if you want to try it out, let us know here if that works.

I cloned the repo & made a minor change (see below) to the kodi.py file & it seems to be working fine for me. I haven't committed the change as I didn't want to break anything for anyone using the older (v2) version of Python

import six
try:
import configparser
except:
#from six.moves import configparser
from six.moves.configparser import ConfigParser

from num2words import num2words
from fuzzywuzzy import fuzz, process
from configparser import SafeConfigParser
#from ConfigParser import SafeConfigParser
from .cache import KodiCache

[m0ngr31]

You probably don't even need six right? Couldn't you just do:

try:
  from ConfigParser import SafeConfigParser
except:
  import configparser as SafeConfigParser

And that's why i'm not a python developer!
That worked fine for me.
