> [Python] Add Array.to_numpy functions
> -------------------------------------
>                 Key: ARROW-2295
>                 URL: https://issues.apache.org/jira/browse/ARROW-2295
>             Project: Apache Arrow
>          Issue Type: Improvement
>          Components: Python
>            Reporter: Lawrence Chan
>            Priority: Minor
> There are `to_pandas()` functions, but no `to_numpy()` functions. I'd like to 
> propose that we include both.
> Also, `pyarrow.lib.Array.to_pandas()` returns a `numpy.ndarray`, which imho 
> is very confusing :). I think it would be more intuitive for the 
> `to_pandas()` functions to return `pandas.Series` and `pandas.DataFrame` 
> objects, and the `to_numpy()` functions to return `numpy.ndarray` and either 
> a ordered dict of `numpy.ndarray` or a structured `numpy.ndarray` depending 
> on a flag, for example. The `to_pandas()` function is of course welcome to 
> use the `to_numpy()` func to avoid the additional index and whatnot of the 
> `pandas.Series`.
