> >>> sdf = spark.range(10)
> >>> spark.createDataFrame(sdf.tail(5), sdf.schema)
> Traceback (most recent call last):
> File "<stdin>", line 1, in <module>

> File "/.../spark/python/pyspark/sql/connect/dataframe.py", line 162, in
> dtypes
> return [(str(f.name), f.dataType.simpleString()) for f in
> self.schema.fields]
