As suggested by @datapythonista , I've added checks in `ci/code_checks.sh` to look if the pandas is being referenced in a standardized way i.e pandas, not *pandas* or Pandas

@datapythonista my bad, will try my changes locally from now on. > This is not working. We're here to help, but please try your changes locally before submitting a PR.

I'm getting `./ci/code_checks.sh: line 243: RET: command not found`, I can't understand why I'm getting this error. All the checks are using it. 

EDIT : Fixed the error mentioned above, pushing the changes Once again, can you check locally if things are working? This is my 10th time reviewing this PR and it's obvious once more that this is not working. There are more than 100 cases of the work `Pandas` in `doc/`, and your changes are not detecting those. No need for your PRs to be perfect, but can you please stop proposing changes that you didn't try locally even once to see if they run without errors or they make sense? Thank you @joybhallaa are you still working on this? take Closing this looks like @willie3838 is looking
