 @datapythonista @jorisvandenbossche 

how does this look? I was taking a look at it yesterday, as I'm not sure in windows the single quotes will handle backslashes well. But unrelated to the ticket I'm getting a segmentation fault when running sphinx-built. Will comment on the ticket with feedback when I manage to test it. Can't test on Windows at the moment, but for linux this patch works nicely and fixes the problem for me. @ThiviyanThanapalasingam seems like in Windows the paths need to be escaped with double quotes (the backlash is interpreted as an escape character like in `\n`).

Besides that, I personally find it's not very readable to use backslashes to escape the quotes. Meaning that instead of `'\'{}\''` I think it'd be more clear to use `"'{}'"`. Or now that we need to change to double quotes, the opposite: `'"{}"'`.

Also, I see that there are several paths that are built like `source/*.rst` (instead of `os.path.join('source', '*.rst')`. I couldn't try, but I guess sphinx is failing to exclude these files like in unix systems. Do we want to open an issue for making the script work in Windows @jreback?

 @ThiviyanThanapalasingam do you have time to update the PR based on the feedback I provided? Yes, I can do that. @datapythonista Have you opened another issue for making the script work in Windows?  No, I think it should be just the one you opened. @datapythonista ? @ThiviyanThanapalasingam can you update the PR based on the previous feedback? Hello @ThiviyanThanapalasingam! Thanks for updating the PR.

 - There are no PEP8 issues in the file [`doc/make.py`](https://github.com/ThiviyanThanapalasingam/pandas/blob/a919eff8df2cca0258e615c7dffa8fe8f2d7be33/doc/make.py) !

 Made the updates to this PR. But seems like there is a new unrelated problem when the path contains whitespaces: #22836

I think that can be addressed in a separate PR. I would merge this on green, but happy to close this and take care of both problems in a new PR. Let's do that in a separate PR

@ThiviyanThanapalasingam thanks for the original PR!
