Alessandro Molina created ARROW-13239:
-----------------------------------------
Summary: [Doc][Python] Dataset.head function doesn't mention
required argument
Key: ARROW-13239
URL: https://issues.apache.org/jira/browse/ARROW-13239
Project: Apache Arrow
Issue Type: Bug
Components: Documentation, Python
Affects Versions: 4.0.1
Reporter: Alessandro Molina
Fix For: 5.0.0
It seems that some function signatures are wrongly reported in the
autogenerated reference.
I found at least one instance in {{pyarrow.dataset.Dataset.head}} which is
documented as a function without any argument (
https://arrow.apache.org/docs/python/generated/pyarrow.dataset.Dataset.html#pyarrow.dataset.Dataset.head
) but in reality it requires one argument (
https://github.com/apache/arrow/blob/master/python/pyarrow/_dataset.pyx#L477 )
I tested also by building documentation locally and the argument is not listed.
