Pycodestyle: Should this line trigger some sort of linting error?

[asottile]

I had a hard time finding something in pep8 that would forbid this (and pycodestyle itself doesn't trigger a lint) but deep down inside I feel it surely should :)

[(a,)for a in y]

Maybe something like "expected spaces around keyword for"?

[sigmavirus24]

but deep down inside I feel it surely should

I feel the same.

This should probably be a new check altogether though.

This is a grey area as I noted in a similar case https://github.com/PyCQA/pycodestyle/issues/570

But [pep 8] doesnt address when unassigned data-structures are used immediately near a keyword like if or for.

I suspect this should be a non-controversial update to PEP 8.

Another (related) strange one:

from .import bar

(works the same as from . import bar)

[FichteFoll]

Is that supposed to be from .import bar?

[asottile]

yep, woops, edited

[hoylemd]

Would the rule here be 'all keywords must be preceded and followed by one space character'?

Another related case:

try:
    ...
except(IOError,):
    ...
