DOC: Add section on using in operator with Series, DataFrame

[danielballan]

closes #5571

[jorisvandenbossche]

If you want that the output of the code is generated automatically, then you have to change .. code-block:: to .. ipython::, and leave out the >>> (the ipython_directive, see http://pandas.pydata.org/pandas-docs/stable/contributing.html#about-the-pandas-documentation).

Off course you can also use code-block, but then you need to paste the exact console input and output in there.

Revised. Thanks, @jorisvandenbossche .

@jorisvandenbossche looks fine to me

[jorisvandenbossche]

Should be a string? ('b')

[danielballan]

Yes. I'll set up doc building on my local machine so I check these things. Sorry for putting you through so many iterations on this.

[danielballan]

I haven't got sphinx working on pandas locally, so I haven't verified this. But the issues discussed above have been fixed.

[jorisvandenbossche]

Looking good (and you can always see the result after a while on http://pandas-docs.github.io/pandas-docs-travis/ to check if everything is OK). Thanks!
