[jira] [Updated] (ARROW-11646) [Python] Allow to create
BooleanArray from a list of 0 and 1
[ https://issues.apache.org/jira/browse/ARROW-11646?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
quentin lhoest updated ARROW-11646:
-----------------------------------
Description:
Hi everyone !
Currently one can create a BooleanArray using these ways:
{code:python}
pa.array([False, True, True, False])
pa.array(np.array([0, 1, 1, 0]), type=pa.bool_())
pa.array([0, 1, 1, 0]).cast(pa.bool_())
{code}
But creating it this way fails:
{code:python}
pa.array([0, 1, 1, 0], type=pa.bool_())
{code}
---------------------------------------------------------------------------
ArrowInvalid Traceback (most recent call last)
<ipython-input-2-e132766d7a68> in <module>
----> 1 a = pa.array([0, 1, 1, 0], type=pa.bool_())

~/.virtualenvs/hf-datasets/lib/python3.7/site-packages/pyarrow/array.pxi in pyarrow.lib._sequence_to_array()

~/.virtualenvs/hf-datasets/lib/python3.7/site-packages/pyarrow/error.pxi in pyarrow.lib.check_status()
ArrowInvalid: Could not convert 0 with type int: tried to convert to boolean

Thanks in advance for the help
