pyspark.sql.functions.sequence(start, stop, step=None)

Generate a sequence of integers from start to stop, incrementing by step. If step is not set, incrementing by 1 if start is less than or equal to stop, otherwise -1.

New in version 2.4.0.

Examples

>>> 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])]
