from pyspark.databricks.sql import functions as dbf
df = spark.createDataFrame([('LINESTRING(1 2,3 4,5 6)',)], ['wkt'])
df.select(dbf.st_asewkt(dbf.st_endpoint(dbf.st_geogfromtext('wkt'))).alias('result')).collect()

Output

[Row(result='SRID=4326;POINT(5 6)')]

Python

from pyspark.databricks.sql import functions as dbf
df = spark.createDataFrame([('LINESTRING ZM (1 2 3 4,5 6 7 8)',)], ['wkt'])
df.select(dbf.st_asewkt(dbf.st_endpoint(dbf.st_geomfromtext('wkt', 4326))).alias('result')).collect()
