I am trying to learn about asyncio for a websockets client. Every piece of code I try gets the following error:
RuntimeError: asyncio.run() cannot be called from a running event loop
I have tried the most simple code and it always gives that RuntimeError. I tried installing the full anaconda distribution again, etc, and can′t find what the problem might be.
I am using Spyder 3.3.3 with Python 3.7.3
An example of code that should work:
import asyncio
async def main():
print('hello')
await asyncio.sleep(1)
print('world')
asyncio.run(main())
Error message:

File "C:UsersjmartAnaconda3libsite-packagesspyder_kernelscustomizespydercustomize.py", line 110, in execfile
