> [Python] Array constructor doesn't support arrow scalars.
> ---------------------------------------------------------
>
> Key: ARROW-18432
> URL: https://issues.apache.org/jira/browse/ARROW-18432
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Python
> Affects Versions: 10.0.1
> Reporter: A. Coady
> Priority: Minor
>
> {code:python}
> pa.array([pa.scalar(0)])
> ArrowInvalid: Could not convert <pyarrow.Int64Scalar: 0> with type
> pyarrow.lib.Int64Scalar: did not recognize Python value type when inferring
> an Arrow data type
> pa.array([pa.scalar(0)], 'int64')
> ArrowInvalid: Could not convert <pyarrow.Int64Scalar: 0> with type
> pyarrow.lib.Int64Scalar: tried to convert to int64{code}
> It seems odd that the array constructors don't recognize their own scalars.
> In practice, a list of scalars has to be converted with `.as_py()` just to be
> converted back, and that also loses the type information.
