Create PySpark DataFrame from list of tuples

In this article, we are going to discuss the creation of a Pyspark dataframe from a list of tuples. 

To do this, we will use the createDataFrame() method from pyspark. This method creates a dataframe from RDD, list or Pandas Dataframe. Here data will be the list of tuples and columns will be a list of column names.

Syntax:

dataframe = spark.createDataFrame(data, columns)

Example 1:

Python3

# importing module
import pyspark

# importing sparksession from
# pyspark.sql module
from pyspark.sql import SparkSession

# creating sparksession and giving
# an app name
spark = SparkSession.builder.appName('sparkdf').getOrCreate()

# list of tuples of college data
data = [("sravan", "IT", 80),
        ("jyothika", "CSE", 85),
        ("harsha", "ECE", 60),
        ("thanmai", "IT", 65),
        ("durga", "IT", 91)]

# giving column names of dataframe
columns = ["Name", "Branch", "Percentage"]

# creating a dataframe
dataframe = spark.createDataFrame(data, columns)

# show data frame
dataframe.show()

Output:

Example 2:

Python3

# importing module
import pyspark

# importing sparksession from
# pyspark.sql module
from pyspark.sql import SparkSession

# creating sparksession and giving
# an app name
spark = SparkSession.builder.appName('sparkdf').getOrCreate()

# list of tuples of plants data
data = [("mango", "AP", "Guntur"),
        ("mango", "AP", "Chittor"),
        ("sugar cane", "AP", "amaravathi"),
        ("paddy", "TS", "adilabad"),
        ("wheat", "AP", "nellore")]

# giving column names of dataframe
columns = ["Crop Name", "State", "District"]

# creating a dataframe
dataframe = spark.createDataFrame(data, columns)

# show data frame
dataframe.show()

Output:

Example 3:

Python code to count the records (tuples) in the list

Python3

# importing module
import pyspark

# importing sparksession from
# pyspark.sql module
from pyspark.sql import SparkSession

# creating sparksession and giving
# an app name
spark = SparkSession.builder.appName('sparkdf').getOrCreate()

#list of tuples of plants data
data = [("mango", "AP", "Guntur"),
        ("mango", "AP", "Chittor"),
        ("sugar cane", "AP", "amaravathi"),
        ("paddy", "TS", "adilabad"),
        ("wheat", "AP", "nellore")]

# giving column names of dataframe
columns = ["Crop Name", "State", "District"]

# creating a dataframe
dataframe = spark.createDataFrame(data, columns)

#count records in the list
dataframe.count()

Output:
