in pyarrow.array
Key: ARROW-9451
URL: https://issues.apache.org/jira/browse/ARROW-9451
Project: Apache Arrow
Issue Type: Bug
Components: Python
Reporter: Wes McKinney
Fix For: 1.0.0
See
{code}
In [12]: pa.array(['5'], type='uint32')
Out[12]:
<pyarrow.lib.UInt32Array object at 0x7fabbdb1edc8>
[
5
]
{code}
Also:
{code}
In [9]: pa.scalar('5', type='uint8')
Out[9]: <pyarrow.UInt8Scalar: 5>
In [10]: pa.scalar('5', type='uint16')
Out[10]: <pyarrow.UInt16Scalar: 5>
In [11]: pa.scalar('5', type='uint32')
Out[11]: <pyarrow.UInt32Scalar: 5>
{code}
But:
{code}
In [13]: pa.array(['5'], type='int32')
