pyspark.sql.functions.zip_with(left: ColumnOrName, right: ColumnOrName, f: Callable[[pyspark.sql.column.Column, pyspark.sql.column.Column], pyspark.sql.column.Column]) → pyspark.sql.column.Column[source]

Merge two given arrays, element-wise, into a single array using a function. If one array is shorter, nulls are appended at the end to match the length of the longer array, before applying the function.

New in version 3.1.0.

Changed in version 3.4.0: Supports Spark Connect.

leftColumn or str

name of the first column or expression

rightColumn or str

a binary function (x1: Column, x2: Column) -> Column... Can use methods of Column, functions defined in pyspark.sql.functions and Scala UserDefinedFunctions. Python UserDefinedFunctions are not supported (SPARK-27052).


array of calculated values derived by applying given function to each pair of arguments.
