OpenAI gym: How to get complete list of ATARI environments

Question

I have installed OpenAI gym and the ATARI environments. I know that I can find all the ATARI games in the documentation but is there a way to do this in Python, without printing any other environments (e.g. NOT the classic control environments)

Answer 1

You can achieve this by calling list_games() on atari_py:

>>> import atari_py as ap
>>> game_list = ap.list_games()
>>> print(sorted(game_list))
<<< ['adventure',
     'air_raid',
     'alien',
     'amidar',
     'assault',
     'asterix',
     'asteroids',
     'atlantis',
     'bank_heist',
     'battle_zone',
     'beam_rider',
     'berzerk',
     'bowling',
     'boxing',
     'breakout',
     'carnival',
     'centipede',
     'chopper_command',
     # ...
     ]
