all python files are now formated with black (#23)

* all python files are now formated with black

NOTE:
some configurations where necessary. flake8 line-length has to be set to 88
which is the default for black. but this was not enough some lines of black
where formated longer then 88 characters. found flake8-bugbear with B950.

with that and in combination with ignore=E501 it is possible to ignore long
lines, but if there are lines to long it will still point it out.

further also for isort some configuration was necessary

* ext removed unnecessary commented import statement

* generators add pragma: no cover to increase code coverage

NOTE:
this should be corrected with a real test in one of the next commits

* fixed the syntax.
