How to replace asyncio.get_event_loop() to avoid the DeprecationWarning?

Hi,

Instead of getting the event loop, use asyncio.run() to execute your main coroutine. This function automatically creates a new event loop, runs the coroutine, and closes the loop afterward. This is the recommended approach for executing top-level coroutines.

import asyncio

async def main():
    # Your async code here
    pass

asyncio.run(main())

If you need to work with multiple event loops or require more control, you can create a new event loop manually using asyncio.new_event_loop() and set it as the current event loop using asyncio.set_event_loop().

import asyncio

loop = asyncio.new_event_loop()
asyncio.set_event_loop(loop)

async def main():
    # Your async code here
    pass

loop.run_until_complete(main())
loop.close()

If you’re within an already running coroutine and need to access the current event loop, use asyncio.get_running_loop(). This method retrieves the event loop that is currently running without the risk of deprecation warnings.

import asyncio

async def example_coroutine():
    loop = asyncio.get_running_loop()
    # Your async code here
    pass

asyncio.run(example_coroutine())
