pycodestyle ``# noqa`` is selectively ignored

[clinssen]

pep8 was replaced by pycodestyle in #1132. Unfortunately, pycodestyle does not allow a # noqa inline comment to suppress certain errors; see https://github.com/PyCQA/pycodestyle/blob/master/docs/intro.rst. This is by design and unlikely to change any time soon.

This means that (some) existing lines containing # noqa need to be refactored, because the formatting errors on those lines are no longer being ignored. For a concrete example, see the matrix formatting in

nest-simulator/pynest/examples/clopath_synapse_spike_pairing.py

Line 73 in c545255

[ 20.0, 120.0, 220.0, 320.0, 420.0], # noqa

There are several options here:

• Switch from pycodestyle to flake8, which does not have this restriction
• Replace the line-scope noqas with a file-scope noqa
• Store the matrices in a textfile and use numpy.loadtxt()
• (probably more...)

I would suggest to switch to flake8. There are just some cases where noqa is sensible.

@clinssen: Sorry that I've overlooked this one and might have sounded like I discovered this issue in our recent meeting. That was not my intention.
