-----------------------------------------
Summary: [Python]
Key: ARROW-9376
URL: https://issues.apache.org/jira/browse/ARROW-9376
Project: Apache Arrow
Issue Type: Bug
Components: Python
Affects Versions: 0.17.1
Reporter: Athanassios Hatzis
h3. First try
{code:python}
data = [pa.array([1, 2, 3, 4]), pa.array(['foo', 'bar', 'baz', None]),
pa.array([True, None, False, True])]
batch = pa.RecordBatch.from_arrays(data, ['f0', 'f1', 'f2'])
{code}
Hi, I use PyCharm IDE for development and I am getting the following inspection
description when I write this piece of code above in the editor.
_Expected type 'RecordBatch', got 'List[Union[Union[ChunkedArray, Array],
Any]]' instead_
_Inspection info: This inspection detects type errors in function call
expressions. Due to dynamic dispatch and duck typing, this is possible in a
limited but useful number of cases. Types of function parameters can be
specified in docstrings or in Python 3 function annotations._
h3. Second try
{code:python}
batch = pa.RecordBatch.from_arrays(data, names=['f0', 'f1', 'f2']){code}
Then you get an insection descriptions
_Parameter 'list_arrays' unfilled_
_Passing list instead of pyarrow.lib.RecordBatch.RecordBatch. Is this
intentional?_
h3. Third try
{code:python}
batch = pa.RecordBatch.from_arrays(list_arrays=data, names=['f0', 'f1', 'f2'])
{code}
Then you get an insection description and a type error
_Parameter 'self' unfilled_
_TypeError: from_arrays() takes at least 1 positional argument (0 given)_
Similar response, behaviour happens with the pa.Table.from_arrays
