Step 1: First of all, import the required libraries, i.e. Applies a function to every key-value pair in a map and returns a map with the results of those applications as the new values for the pairs. split convert each string into array and we can access the elements using index. It is done by splitting the string based on delimiters like spaces, commas, and stack them into an array. There are three ways to explode an array column: Lets understand each of them with an example. Lets look at a sample example to see the split function in action. Most of the problems can be solved either by using substring or split. In this example, we have created the data frame in which there is one column Full_Name having multiple values First_Name, Middle_Name, and Last_Name separated by a comma , as follows: We have split Full_Name column into various columns by splitting the column names and putting them in the list. This gives you a brief understanding of using pyspark.sql.functions.split() to split a string dataframe column into multiple columns. Step 11: Then, run a loop to rename the split columns of the data frame. New in version 1.5.0. This is a part of data processing in which after the data processing process we have to process raw data for visualization.
