Python formatting fixes

[johngrantuk]

I setup vscode extensions with auto formatting and integrated linters so I don’t need to run pylint/black commands
A lot of warnings appeared - nothing critical, but it would be nice to handle them at some point 🙃
In case you’d like to apply the same on your vscode, all you’d need is:
enable python extension (which has pylint integrated)
create a .vscode folder containing a settings.json file with this:
{
"editor.defaultFormatter": "ms-python.black-formatter",
"editor.formatOnSave": true
}
3. you might need to restart vscode
(all this inside python folder - not balancer-maths folder)

And I also setup a launch.json file within .vscode folder that allows to run a single test file and enables debugging with breakpoints
