ENH: New method "ends" as a combination of “head” and "tail"

[JoergVanAken]

Feature Type

• Adding new functionality to pandas

• Changing existing functionality in pandas

• Removing existing functionality in pandas

Problem Description

I often work with time series and want to see at a glance where and how they begin and end.

Feature Description

That's why I registered an "ends" accessor, which provides me with both ends in one call as a combination of "head" and "tail". It's really simple, but very usefull to me:

class _EndsAccessor:
    def __init__(self, pandas_obj):
        self._obj = pandas_obj

    def __call__(self, n=2):
        return pd.concat([self._obj.head(n), self._obj.tail(n)])

@pd.api.extensions.register_dataframe_accessor("ends")
class EndsAccessorDataframe(_EndsAccessor):
    pass


@pd.api.extensions.register_series_accessor("ends")
class EndsAccessorSeries(_EndsAccessor):
    pass

Alternative Solutions

We leave it as it is and I continue using the solution shown above.

Im skeptical of this. The API is already big and we generally avoid adding methods with an easy alternative already available. Will leave this open in case others disagree.
