To split multiple array column data into rows pyspark provides a function called explode(). Example 1: Split column using withColumn () In this example, we created a simple dataframe with the column DOB which contains the Since Spark 2.0, string literals (including regex patterns) are unescaped in our SQL parser. Generate a sequence of integers from start to stop, incrementing by step. Parameters str Column or str a string expression to Suppose we have a DataFrame that contains columns having different types of values like string, integer, etc., and sometimes the column data is in array format also. You simply use Column.getItem () to retrieve each Following is the syntax of split () function. Example 3: Splitting another string column. Lets use withColumn() function of DataFame to create new columns. Instead of Column.getItem(i) we can use Column[i] . Later on, we got the names of the new columns in the list and allotted those names to the new columns formed.
