Python run error in Jupyter Notebook

[sanketh-1011]

asyncio.run() cannot be called from a running event loop

I'm getting this error while running the python file in jupyter notebook, anybody know how to solve it?

In jupyter notebook, ipykernel is used to run Python code and it uses asyncio for asynchronous code execution within cells. Therefore, you won't be able to run two asyncio at the same time.

However, you can implement await in your code.

if __name__ == "__main__":
    ascii_art()
    await main()

If you are using jupyter notebook specifically, you do not need if __name__ == "__main__": wrapper block.

ascii_art()
await main()

Make sure you run !pip install aiohttp package before running.
