The count is the length of the string in which we are working for a given DataFrame.īy This method, the value of the String is extracted using the index and input value in PySpark. A different offset and count is created that basically is dependent on the input variable provided by us for that particular string DataFrame. A new string is created with the same char while calling the substring method. String basically is a char having the character of the String with an offset and count. The return type of substring is of the Type String that is basically a substring of the DataFrame string we are working on.Ī certain Index is specified starting with the start index and end index, the substring is basically the subtraction of End – Start Index. The substring function is a String Class Method. Let us see somehow the SubString function works in PySpark:.
The withColumn function is used in PySpark to introduce New Columns in Spark DataFrame.Ī.Name is the name of column name used to work with the DataFrame String whose value needs to be fetched. L:- The Length to which the Substring needs to be extracted.ī=a.withColumn(“Sub_Name”,a.Name.substr(1,3)) S:- The starting Index of the PySpark Application.
