What is PEP8's E128: continuation line under-indented for visual indent?

Question

Just opened a file with Sublime Text (with Sublime Linter) and noticed a PEP8 formatting error that I\'d never seen before. Here\'s the text:

urlpatterns = p         


        

Answer 1

This goes also for statements like this (auto-formatted by PyCharm):

    return combine_sample_generators(sample_generators['train']), \
           combine_sample_generators(sample_generators['dev']), \
           combine_sample_generators(sample_generators['test'])

Which will give the same style-warning. In order to get rid of it I had to rewrite it to:

    return \
        combine_sample_generators(sample_generators['train']), \
        combine_sample_generators(sample_generators['dev']), \
        combine_sample_generators(sample_generators['test'])
