The if-else is another method to implement switch case replacement. It is used to determine whether a specific statement or block of statements will be performed or not, i.e., whether a block of statements will be executed if a specific condition is true or not. Where if statements must be provided a truthy or falsey value, match-case statements can match against the shape/structure of an object in a concise way. Consider the following example from the PEP: def make_point_3d(pt): match pt: case (x, y): return Point3d(x, y, 0) case (x, y, z): return Point3d(x, y, z)Using “ when otherwise ” on Spark DataFrame. when is a Spark function, so to use it first we should import using import org.apache.spark.sql.functions.when before.
