>>> df1 = spark.createDataFrame([(-2, 2)], ('C1', 'C2')) >>> df1.select(sequence('C1', 'C2').alias('r')).collect() [Row(r=[-2, -1, 0, 1, 2])] >>> df2 = spark.createDataFrame([(4, -4, -2)], ('C1', 'C2', 'C3')) >>> df2.select(sequence('C1', 'C2', 'C3').alias('r')).collect() [Row(r=[4, 2, 0, -2, -4])]
