PySpark RDD's count(~) method returns the number of values in the RDD as an integer.

Parameters

This method does not take in any parameters.

Return Value

An integer (int).

Examples

Consider the following PySpark RDD:

rdd = sc.parallelize(["A","B","A","B"])
rdd.collect()
['A', 'B', 'A', 'B']

Here, we are using the parallelize(~) method to create a PySpark RDD.

Getting the number of values in PySpark RDD

To get the number of elements in the RDD, use the count() method:

rdd.count()
