sum¶

ColExpr.sum( *, partition_by: Col | ColName | str | Iterable[Col | ColName | str] | None = None, filter: ColExpr[Bool] | Iterable[ColExpr[Bool]] | None = None, ) → ColExpr[Int][source]¶
ColExpr.sum( *, partition_by: Col | ColName | str | Iterable[Col | ColName | str] | None = None, filter: ColExpr[Bool] | Iterable[ColExpr[Bool]] | None = None, ) → ColExpr[Float]
ColExpr.sum( *, partition_by: Col | ColName | str | Iterable[Col | ColName | str] | None = None, filter: ColExpr[Bool] | Iterable[ColExpr[Bool]] | None = None, ) → ColExpr[Int]: Computes the sum of values in each group.
