So for state you can't access it directly this way - you have to eg. get a specific entity using state.get(...) etc. - you can't inspect it as if it was a standalone object and I think there's also no such thing as get_history() on it. See here for reference on how to use it and here the disclaimer. Remember pyscript is emulating python's behavior in order to provide async operations out of the box to not block home assistant's main thread (it's not "real" python so some things might work differently from what you are used to - to escape this behavior check out @pyscript_compile but beware of its limitations or try creating a native python package alongside pyscript which you can then import into your scripts - you can find out how here).

File operations such as file and open should not be used at all. See here. You should use an async version of these. Here's some information on how to do that

@IgnusG - excellent answer - thanks!
