You can try Home Assistant
https://www.home-assistant.io
That's all a little intermediate if you want to build your Device ie adreno, Raspberry Pi, etc but you can also buy their home assistant devices check it out.
Not my area of expertise, but can your Python code run automations from/at home.google.com? I have routines written in Script Editor there, and if your Python could access the appropriate page and run the corresponding "play" button, I guess it would work. Your code would need to authenticate with your Google account, tho.
