Question

What do you understand by startsWith() and endsWith() methods in PySpark?

Answer 1

The startsWith() and endsWith() methods in PySpark belong to the Column class and are used to search DataFrame rows by checking if the column value starts with some value or ends with some value. Both are used for filtering data in applications.

1. startsWith() method: This method is used to return a Boolean value. It shows TRUE when the column's value starts with the specified string and FALSE when the match is not satisfied in that column value.
2. endsWith() method: This method is used to return a Boolean value. It shows TRUE when the column's value ends with the specified string and FALSE when the match is not satisfied in that column value. Both methods are case-sensitive.
