Hello @RanDan363! Thanks for updating this PR. We checked the lines you've touched for [PEP 8](https://www.python.org/dev/peps/pep-0008) issues, and found:



There are currently no PEP 8 issues detected in this Pull Request. Cheers! :beers: 

##### Comment last updated at 2019-10-21 15:16:30 UTC Looks like you need to run black on the changed file. Also can you post a screenshot of the new docs to be sure this is working? Should be able to generate via `python make.py --single pandas.Series.eq` from the docs folder sorry, not sure exactly what you want me to do..
Could you briefly elaborate please? To solve the CI problem run `black pandas/core/ops/docstrings.py` and push back up

To check the doc can you run `python make.py --single pandas.Series.eq` from the docs folder and share a screenshot of generated output that appears in docs/build/html/reference/api/pandas.core.series.Series.eq.html is that what you meant?
