'StructType' object has no attribute 'toDDL'

Question

I'm running this script with spark 2.4.3 & python 3.6.10

columns = ["language","users_count"]
data = [("Java", "20000"), ("Python", "100000"), ("Scala", "3000")]
spark = SparkSession.builder.appName('SparkByExamples.com').getOrCreate()
rdd = spark.sparkContext.parallelize(data)
df = rdd.toDF()
print(df.schema.toDDL)

AttributeError: 'StructType' object has no attribute 'toDDL'

The java documentation mentions that toDDL function is available from spark 2.4.0, which is not in the python documentation.

Is there any other way to use this java function from python?

Answer 1

You can call the toDDL method on the Java dataframe object:

df._jdf.schema().toDDL()
