Joris Van den Bossche updated ARROW-15131:
------------------------------------------
Description:
Small example I ran into:
{code:python}
>>> arr = pa.array(['a', 'b', 'c', 'd'])
>>> pc.is_in(arr, ['a', 'c'])
...
TypeError: "['a', 'c']" is not a valid value set
{code}
That's not a super friendly error message (it was not directly clear what is
not "valid" about this). Passing {{pa.array(['a', 'c'])}} explicitly works, but
I expected that the kernel would try this automatically (as we also convert the
first array argument to an array).
