Update supported versions of Python

[pydanny]

Doesn't officially support Python 3.6 or 3.7

[wadleo]

We now support version 3.6 #69 .

@bilesanmiahmad can you work on this to make it support version 3.7 and 3.8?

[bilesanmiahmad]

@wadleo sure I can work on this

[wadleo]

@bilesanmiahmad you can look at this PR #69 for guidance.

Also, you may have to recreate your virtualenv with the -p flag and pass the python version to it. Since you are using Ubuntu, it will be look like
virtualenv -p python3.8 env

Then you can run the do python setup install and you can now test the app to see it it will be compatible with this python version

OK, thank you for the guidelines.
