Usage

import gym
import gym_toytext

env = gym.make("GuessingGame-v0")
observation, info = env.reset()
low, high = env.action_space.low, env.action_space.high
while True:
    action = (low + high) / 2.
    observation, reward, termination, truncation, info = env.step(action)
    if termination or truncation:
        break
    if observation == 1:
        low = action
    elif observation == 3:
        high = action
env.close()
