to achieve real-time updates in a react native application with a python backend, you can utilize websockets for bidirectional communication. websockets allow for real-time data exchange between the client (react native app) and the server (python backend).

here's a step-by-step tutorial on how to implement real-time updates using websockets:

1. *setting up the python websocket server:*

you can use the `websockets` library in python to create a websocket server. install the library using pip:



here's a simple example of a python websocket server that echoes messages back to the client:



2. *setting up the react native client:*

you can use libraries like `react-native-websocket` to establish a websocket connection in your react native app. install the library using npm:



here's an example of how you can connect to the websocket server in your react native app:



3. *testing the real-time updates:*

start the python websocket server by running the python script. then, launch your react native app and you should see the message 'connected to websocket server' in the console. you can send messages from the server to the client by calling `websocket.send()` in the python script.

4. *handling real-time updates:*

you can now implement logic in your react native app to handle real-time updates received from the websocket server. update the ui based on the data received from the server to reflect real-time changes.

by following this tutorial and adapting the websocket server and react native client code to your specific use case, you can achieve real-time updates in your react native application with a python backend.
