The Python DBAPI driver throws an exception when fetching EXPLAIN query results:

import monetdb.sql
db = monetdb.sql.connect(database="demo")
cursor = db.cursor()
cursor.execute("explain select count(*) from sys.tables")
31

File "monetdb/sql/cursors.py", line 205, in fetchone
result = self.__rows[self.rownumber - self.__offset]
IndexError: list index out of range
