@adibyte95 in python the order of a dict's keys will not be the same between runs. This is because it uses a hashmap under the hood. I would recommend explicitly referring to a quantity you require by the key name. Eg: state["next_pipe_top_y"].

@ntasfi by using an ordered dictionary as compared to ordinary dictionary the keys will be in the same position as they were inserted and will not change during different runs. i know that in an dictionary a value can be easily found through its corresponding key, but if someone tries to use only the values as in my case they will get confused, so i think this is more elegant this way.
