Python is a roller coaster in Adventure Realm at Efteling. While it's not the best, it is also recommended.
A standard Vekoma steel looping coaster that has a similar track to Magic Mountain at Gardaland. Don't expect anything groundbreaking, but Python still packs a fun little bite in its two loops and double corkscrew. It is also the oldest, steelen rollercoaster with inversions in Europe. It was built in 1981 and it is still operating.
