Documentation: Indexing and selecting data¶
fixes #41629 

Hi @LukeTonin, how does this look?
let me know if this needs any changes!
Thanks

Just commenting that medium.com is a paid article provider. That link is not always available, depending upon how many "free" articles you are permitted view in a period of time. Maybe can be added this https://stackoverflow.com/a/41130329/10491422 due it's a common limitation that causes confusion, instead of a medium blog  Sure! I can do that  @rbrishabh That looks good. Agreed with the point about medium not always being accessible. A "free" resource would be better. Thanks! @LukeTonin made that `url` change can u make this into a :note: to make this more prominent

text looks good

ping when greenish There is already a [warning block](https://github.com/pandas-dev/pandas/pull/41645/files#diff-faa1b06767c38c506752127df49ec52fb61d6d9a0ad834ffd6fb24618035e070R207-R219) with this information in the same section; wouldn't a note linking out to an external resource be redundant?

Also, after changing what the link goes to, the context ("10 reasons") no longer corresponds. yeah i see this is already adequately documented: https://pandas.pydata.org/pandas-docs/dev/user_guide/indexing.html#attribute-access, thanks @mwaskom 

thanks for the effort @rbrishabh
