> In the spark.python.pyspark.sql.functions module, at the {{date_format}}
> method's doctest, there is a typo in the year format.
> Instead of '{{{}MM/dd/yyy'{}}}, it should be {{'MM/dd/yyyy'}} as the expected
> output{{{}[Row(date='04/08/2015')]{}}} indicates the following format
> {{"MM/dd/yyyy".}}
>
> From the official documentation:
> !image-2023-10-19-19-46-22-918.png|width=633,height=365!
> {code:java}
> df = spark.createDataFrame([('2015-04-08',)], ['dt'])
> df.select(date_format('dt', 'MM/dd/yyy').alias('date')).collect()
> [Row(date='04/08/2015')]
> {code}
>
> As a solution, I proposed the PR [https://github.com/apache/spark/pull/43442].
