The `__future__` we relied on is now, where the 3 specific things are
all included [since Python 3.0](https://docs.python.org/3/library/__future__.html):
* absolute_import
* print_function
* unicode_literals
* division
These import statements are no-ops and are no longer necessary.
Replace the project global linting rule excludes (as defined in .pep8) with
fine-grained "# noqa" annotations.
By using noqa annotation the excludes are made on a per line basis instead of
globally.
These annotations are used where we make deliberate deviations from the standard
linting rules.
To lint the Python code in the project:
$ flake8
To install flake8:
$ pip install flake8
See https://flake8.readthedocs.org/en/latest/ for details.
To enable checking of the PEP-8 naming conventions, install the optional
extension pep8-naming:
$ pip install pep8-naming
To enable checking of blind "except:" statements, install the optional
extension flake8-blind-except:
$ pip install flake8-blind-except
To enable checking of import statement order, install the optional
extension flake8-import-order:
$ pip install flake8-import-order
Fixes:
* Unused import
* Redundant backslash
* Use of discouraged if not x in y
* Use of deprecated form of raising exceptions
Follow-up to PR #655 as requested by @gribozavr
This makes it clearer via their name what the two scripts are meant to
be used for.
As a recap:
1. pipeline_generator.py is meant for generating pass pipeline json
files.
2. pipelines_build_script.py is a script built ontop of
pipeline_generator.py that makes it easy to run build-script with
various pass pipelines that can be generated from
pipeline_generator.py. It is meant to be used on buildbots and for ones
own enjoyment as well.
