Python runtimeerror this event loop is already running in python

in python, a `runtimeerror` with the message "this event loop is already running" is typically encountered when you are trying to start a new asyncio event loop while another event loop is already running. this error occurs when you are attempting to run an asynchronous operation within an existing event loop, but another event loop is already running in the same thread.

here is an example to demonstrate this error:

to avoid this error, you should only run one event loop per thread. if you need to run multiple asynchronous tasks, you can do so within the same event loop, as shown below:

remember to ensure that you are working within the same event loop when running multiple asynchronous tasks to avoid conflicts and `runtimeerror`s related to event loop management.
