name 'policy' is not defined #113

Following the code in the documentation for PettingZoo Multi-Agent API

import sumo_rl
env = sumo_rl.env(net_file='sumo_net_file.net.xml',
                  route_file='sumo_route_file.rou.xml',
                  use_gui=True,
                  num_seconds=3600)  
env.reset()
for agent in env.agent_iter():
    observation, reward, done, info = env.last()
    action = policy(observation)
    env.step(action)

Upon running the code, I get an error name 'policy' is not defined. How to solve that?

It is meant to be substituted with ML algorithm.
