Thanks for the pull request @BoboTiG! Everything looks great!

Do you want me to open a new PR for flake8 fixes? They are not related to my changes but still I can do that work separately :)

Hi @BoboTiG , you are referring to the invalid escape sequence in our documentation build?

Also you referring to the pep8 issues that @pep8speaks reported?

[BoboTiG]

I was referring to the pep8 issues that @pep8speaks reported. I will open a new PR for those specific fixes.

[nabobalis]

I mean't the focus of the changes you've made in this PR?

Also I would be against a separate PR only for pep8 fixes.

[BoboTiG]

Oh OK :)

Changes in this PR are related to general Python code, not specifically about what the documentation build reported.
Those DeprecationWarnings are already converted to SyntaxWarnings in the current Python dev branch and will become SyntaxError in a near future version.

If you want to do pep8 fixes, I would suggest doing them in this PR.

Can you check that these errors are gone in the documentation build (ci/circleci: html-docs)?

[BoboTiG]

OK for PEP8 fixes, will do in that PR.

About doc build: the number of such warnings went from 33 to 5. I need to track the last ones.

[BoboTiG]

OK, fixed all PEP8 errors. For errors reported from docstrings code, I did not want to break anything so I disabled checks using the noqa comment.

The 5 remaining invalid sequences was inside a .rst file. There is now no more such warning in the documenation build :)

Thank you very much @BoboTiG!

My pleasure :)
