>                 URL: https://issues.apache.org/jira/browse/SPARK-37085
>             Project: Spark
>          Issue Type: Improvement
>          Components: PySpark, SQL
>    Affects Versions: 3.1.0, 3.2.0, 3.3.0
>            Reporter: Maciej Szymkiewicz
>            Assignee: Apache Spark
>            Priority: Minor

> There are a few functions that have vararg signature, but can accept a single item ({{list}} or {{tuple}}):
>  - {{def create_map(*cols: "ColumnOrName") -> Column: ...}}
>  - {{def struct(*cols: "ColumnOrName") -> Column: ...}}
>  - {{def array(*cols: "ColumnOrName") -> Column: ...}}
>  - {{def map_concat(*cols: "ColumnOrName") -> Column: ...}}
>  
> We should add overloads of the following form
>  
> {code:python}
> @overload
> def _(cols: Union[List["ColumnOrName"], Tuple["ColumnOrName", ...]]) -> Column:
>     ...
> @overload
> def _(*cols: "ColumnOrName") -> Column:
>     ...
> def _(
>     *cols: Union["ColumnOrName", List["ColumnOrName"], Tuple["ColumnOrName", ...]]
> ) -> Column:
>    ...
> {code}
