Matthew Roeschke created ARROW-16645:
----------------------------------------
Summary: Allow pa.array/pa.chunked_array to infer pa.NA when in a
non pyarrow container
Key: ARROW-16645
URL: https://issues.apache.org/jira/browse/ARROW-16645
Project: Apache Arrow
Issue Type: Improvement
Components: Python
Affects Versions: 7.0.0
Reporter: Matthew Roeschke
Example:
{code:java}
In [15]: import pyarrow as pa
In [16]: pa.array([1, pa.NA])
ArrowInvalid: Could not convert <pyarrow.NullScalar: None> with type
pyarrow.lib.NullScalar: did not recognize Python value type when inferring an
Arrow data type{code}
I would be great if this could be equivalent to
{code:java}
In [17]: pa.array([1, pa.NA], mask=[False, True])
Out[17]:
<pyarrow.lib.Int64Array object at 0x7fe49c172b80>
[
1,
null
]
In [18]: pa.__version__
Out[18]: '7.0.0'{code}
