I'm not sure we need / want to make this change.

jschendel · 2019-05-10T22:42:55Z

Also not sure if we need/want this change, as it adds an additional layer of complexity to maintaining common docstrings. Certainly something we could work around if we want to change the repr but not ideal.

cc @jorisvandenbossche : what are your thoughts here?

jschendel

There are a some additional IntervalArray docstrings that would need to be updated to match the new repr that aren't currently being checked by CI, e.g. from_arrays, from_breaks, etc.

pandas/pandas/core/arrays/interval.py

Lines 252 to 257 in bb0376c

I think there should be a way of reusing the main portion of the docstring, and appending in custom examples. Something similar to the constructor maybe?

pandas/pandas/core/indexes/interval.py

Lines 100 to 124 in bb0376c

Examples

--------

A new ``IntervalIndex`` is typically constructed using

:func:`interval_range`:

>>> pd.interval_range(start=0, end=5)

IntervalIndex([(0, 1], (1, 2], (2, 3], (3, 4], (4, 5]],

closed='right',

dtype='interval[int64]')

It may also be constructed using one of the constructor

methods: :meth:`IntervalIndex.from_arrays`,

:meth:`IntervalIndex.from_breaks`, and :meth:`IntervalIndex.from_tuples`.

See further examples in the doc strings of ``interval_range`` and the

mentioned constructor methods.

jorisvandenbossche · 2019-05-11T12:44:41Z

Personally I think in principle it would be nice to start using the same repr style for all Array classes.
But the docstring sharing is indeed something we first need to think through.
How do we currently do that for DatetimeArray? We don't share docstrings with DatetimeIndex?

jreback · 2019-05-11T19:16:32Z

@TomAugspurger what is your objection here? this de-special cases IntervalArray repr and makes it like all other Arrays, a good thing.

TomAugspurger · 2019-05-11T19:34:08Z

Having to rewrite the docstrings to pass doctests.

@makbigc can you merge master.

working. Give me some more time.

@jschendel Amended. Please tell me if anything is wrong.

jreback · 2019-07-21T00:28:04Z

ok this looks pretty good now; @jschendel

jschendel

Can you add a whatsnew note with previous/current behavior examples to the 1.0 whatsnew since this is technically a backwards incompatible change?

jschendel · 2019-07-24T19:39:02Z

Will review this in more depth later tonight but looks good overall. Would be nice to have an automated way of converting between IntervalArray and IntervalIndex example sections but that can be saved for a follow up.

Since this is an actual python block I don't think you need the In/Out - that may be causing the CI failure

@WillAyd
Thanks for your advice. Otherwise I can't pass the CI tests.

Sorry could have been clearer but just make this `.. ipython:: python`` for the directive. You shouldn't then need the In / Out below and it will render automatically for you (this is typically what we do with new behavior)

In case it helps you should use code-block for the old behavior and the ipython directive for newly introduced behavior. You can see an example of this with the Better Repr for MultiIndex section back in the 0.25 whatsnew
