Can you use a more informative title?

Looks like a .ipynb file got included accidentally? Yes sure I will do that.

And could you please ignore .ipynb file. It accidently got uploaded.

 Thanks.  We can ignore the extra file for now, but you'll need to remove it before this can be merged.

Looks like the lint checker is unhappy about the removed newline.  Can you run `black pandas/core/series.py` Hello @rmunjal29! 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:

 Looks like there is a notebook in the diff - can you remove that?
