adds python 3.7 compatibility

[benjamin-salchow]

I upgraded to Python 3.7 and I could not run your plug-in.

I got the following error: "Plugin Cost Estimation (2.1.3) is not compatible to Python 3.7.3 (compatibility string: >=2.7,<3)."

So I just added the plugin_pythoncompat information and run this plugin. Now it works like a charm with Python 3.7.3 and I had no issue with my OctoPrint setup.

Hi, I just upgraded my octoprint installation to python 3 and would like to install this plugin with python 3 support. Could you tell me how I would do this? I'm sorry I'm a noob to all this, but I'm guessing I would need to merge your changed file with the rest of the files in the plugin before installing it. But I have no idea how I would go about doing that.

I know how to do a few things in the terminal, but I don't know how I would manually download individual files, compile the plugin, then install it.

I understand if it's too much to explain, but if you could point me in the right direction, it'd be greatly appreciated. Thanks!

@fractalsauce basically, @benjamin-salchow forked this plugin to make the changes necessary for it to run under python3. you can find that fork here. https://github.com/benjamin-salchow/OctoPrint-CostEstimation using the "unstall from url" feature in octoprint, you should be able to install the fork :)

@codingcatgirl Oh awesome thanks! I thought that might be the case but I couldn't find a link to the fork anywhere. How would I go about finding said link in the future?

The easiest way would be to merge my fix into the master branch of this repository, then the automatic update of octoprint would work. But I guess this plug-in is not actively maintained any more. My pull request is from march and still not accepted or included.

Yes, as a workaround you can use my fork with the Python 3 fix.

@malnvenshorn could you please check and merge it. Thank you very much :-).

@benjamin-salchow Hey I finally got it working thanks! Just wanted to point out that on your forked page under setup and the bottom, you still have the original link to @malnvenshorn 's version. Took me a sec to figure out why it was still saying it didn't support Python 3 and still wasn't working when I tried to install it in the Plugin manager. Might wanna update that. Anyways thank you all again, problem solved! :D
