             Summary: Use keyword-only syntax for keyword_only methods
                 Key: SPARK-32933
                 URL: https://issues.apache.org/jira/browse/SPARK-32933
             Project: Spark
          Issue Type: Improvement
          Components: PySpark
    Affects Versions: 3.1.0
            Reporter: Maciej Szymkiewicz


Since 3.0, provides syntax for indicating keyword-only arguments ([PEP 3102|https://www.python.org/dev/peps/pep-3102/]).

It is not a full replacement for our current usage of {{keyword_only}}, but it would allow us to make our expectations explicit:


{code:python}
@keyword_only
def __init__(self, degree=2, inputCol=None, outputCol=None):
{code}

{code:python}
@keyword_only
def __init__(self, *, degree=2, inputCol=None, outputCol=None):
{code}
