E122 continuation line missing indentation or outdented

I have what I think may be a bug in flake8. Consider this source file, test.py: open({ 'a': len([1, 2, 3]), 'b': [ 'c' ] }) open({ 'a': False, 'b': [ 'c' ] }) Notice that the two blocks only differ in the call to "len." If I run flake8 on it: $ flake8 test.py test.py:6:5: E122 continuation line missing indentation or outdented It passes without errors if I move the "]" on line 6 to under the open-quote in 'c'. I believe this file should pass flake8 without errors. But, if it doesn't, it should have two errors, not one. Version information: $ python -V Python 3.5.2 $ flake8 --version 3.5.0 (mccabe: 0.6.1, pycodestyle: 2.3.1, pyflakes: 1.6.0) CPython 3.5.2 on Linux Also replicated on a fresh Docker container based on ubuntu:bionic with Python 3.6.4 (nothing installed but the base image, python3, python3-pip, and the pypi version of flake8). Thanks!

Madeleine, That's an excellent find. The underlying bug is in pycodestyle, though. You can report the issue on github.com/PyCQA/pycodestyle Cheers, Sent from my phone with my typo-happy thumbs. Please excuse my brevity On Feb 13, 2018 15:07, "Madeleine Thompson" <madeleineth@gmail.com> wrote:

sorry, that was a bit abrupt: I do think it is a great find, and there may be more info revealed by your investigation that you could add to the issue. I was hoping to find the time to see if I could find and fix the bug, but that hasn't magically materialized so far. ;) On Tue, Feb 13, 2018 at 1:22 PM, Eric Casteleijn <thisfred@gmail.com> wrote:
