dch nguyen updated SPARK-36930:
-------------------------------
Description:
When DF.dtypes is supported, we can use
{code:java}
>>> pdf = pd.DataFrame(
... {"a": [1, 2, 3, 4, 5, 6, 7, 8, 9], "b": [4, 5, 6, 3, 2, 1, 0, 0, 0]},
... )
>>> psdf = ps.from_pandas(pdf)
>>> psdf.dtypes
a int64
b int64
dtype: object
>>> ps.DataFrame[psdf.dtypes]
typing.Tuple[pyspark.pandas.typedef.typehints.NameType, pyspark.pandas.typedef.typehints.NameType]
{code}
