-----------------------------------

             Summary: Support list type for spark.sql.functions.lit
                 Key: SPARK-40271
                 URL: https://issues.apache.org/jira/browse/SPARK-40271
             Project: Spark
          Issue Type: Test
          Components: PySpark
    Affects Versions: 3.4.0
            Reporter: Haejoon Lee


Currently, `pyspark.sql.functions.lit` doesn't support for Python list type as below:


{code:python}
>>> df = spark.range(3).withColumn("c", lit([1,2,3]))
Traceback (most recent call last):
...
: org.apache.spark.SparkRuntimeException: [UNSUPPORTED_FEATURE.LITERAL_TYPE] The feature is not supported: Literal for '[1, 2, 3]' of class java.util.ArrayList.

{code}

We should make it supported.
