pyspark.sql.DataFrame.tail¶

DataFrame.tail(num: int) → List[pyspark.sql.types.Row][source]¶

Returns the last num rows as a list of Row.

Running tail requires moving data into the application’s driver process, and doing so with a very large num can crash the driver process with OutOfMemoryError.

New in version 3.0.0.

Changed in version 3.4.0: Supports Spark Connect.

Parameters

numint: Number of records to return. Will return this number of records or all records if the DataFrame contains less than this number of records.

Returns

list: List of rows

Examples

>>> df = spark.createDataFrame(
...     [(14, "Tom"), (23, "Alice"), (16, "Bob")], ["age", "name"])

>>> df.tail(2)
[Row(age=23, name='Alice'), Row(age=16, name='Bob')]
