How to create a sample Spark dataFrame in Python?

the following code is not working

With single element you need a schema as type

spark.createDataFrame(["10","11","13"], "string").toDF("age")

or DataType:

from pyspark.sql.types import StringType

spark.createDataFrame(["10","11","13"], StringType()).toDF("age")

With name elements should be tuples and schema as sequence:

spark.createDataFrame([("10", ), ("11", ), ("13",  )], ["age"])

Well .. There is some pretty easy method for creating sample dataframe in PySpark

>>> df = sc.parallelize([[1,2,3], [2,3,4]]).toDF()
>>> df.show()
+---+---+---+
| _1| _2| _3|
+---+---+---+
|  1|  2|  3|
|  2|  3|  4|
+---+---+---+

to create with some column names

>>> df1 = sc.parallelize([[1,2,3], [2,3,4]]).toDF(("a", "b", "c"))
>>> df1.show()
+---+---+---+
|  a|  b|  c|
+---+---+---+
|  1|  2|  3|
|  2|  3|  4|
+---+---+---+

In this way, no need to define schema too.Hope this is the simplest way

from pyspark.sql import SparkSession

spark = SparkSession.builder.getOrCreate()
df = spark.createDataFrame([{"a": "x", "b": "y", "c": "3"}])

Output: (no need to define schema)

+---+---+---+
| a | b | c |
+---+---+---+
|  x|  y|  3|
+---+---+---+
