mean¶

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