> Key: ARROW-7218

> Issue Type: Test
> Components: Python
> Reporter: Joris Van den Bossche
> Priority: Minor
> Fix For: 1.0.0

>
> In general, we are fine to accept a list of numpy scalars:
> {code}
> In [12]: type(list(np.array([1, 2]))[0])
> Out[12]: numpy.int64
> In [13]: pa.array(list(np.array([1, 2])))
> Out[13]:
> <pyarrow.lib.Int64Array object at 0x7f51a493e2e8>
> [
> 1,
> 2
> ]
> {code}
> But for booleans, this doesn't work:
> {code}
> In [14]: pa.array(list(np.array([True, False])))
> ---------------------------------------------------------------------------
