How to manually start and stop a thread running blocking code within a Python asyncio event loop?

I have an app that runs in asyncio loop. I wish to start a thread which will execute a piece of blocking code:

def run(self)->bool:
        self._running = True
        while self._running:
        
            #MOVE FORWORD / BACKWORDS
            if kb.is_pressed('x'):
                self.move_car("forward")
            elif kb.is_pressed('w'):
                self.move_car("backward")
            
        return True

until I decide to stop it and manually set the self._running = False by calling:

def stop(self):
    self._running = False

These are both methods of a class controlling the whole operation of a raspberry pi robot-car I made.

I want this to run on a separate thread so that my main application can still listen to my input and stop the thread while the other thread is running in this while loop you can see above.

How can I achieve that?Note For sending the start and stop signal I use http requests but this does not affect the core of my question.

Prop `className` did not match in next js app

I have written a sample code ( Github Link here ). this is a simple next js app, but giving me error when I refresh the page. This seems to be the common problem and I tried the fix provided in the internet but does not seem to fix my issue. The error is Warning: Prop className did not match. Server: "MuiBox-root MuiBox-root-1" Client: "MuiBox-root MuiBox-root-2". Did changes for _document.js, modified _app.js as mentioned in official website and solutions in stackoverflow. but nothing seems to work. Could someone take a look and help me whats wrong with the code? Via Active questions tagged javascript - Stack Overflow https://ift.tt/2FdjaAW
