如何查看OpenAI健身房环境中可用的动作？

import gym

env = gym.make('环境名称')

action_space = env.action_space

if isinstance(action_space, gym.spaces.Discrete):
    # 离散动作空间
    num_actions = action_space.n
    print("可用的动作数量：", num_actions)
elif isinstance(action_space, gym.spaces.Box):
    # 连续动作空间
    action_shape = action_space.shape
    action_low = action_space.low
    action_high = action_space.high
    print("动作空间形状：", action_shape)
    print("动作空间范围：", action_low, "-", action_high)
