I am specifically using python version 3.10 to run a websocket (or any long asyncio process) for a specified period of time which is covered in the python docs. The .wait_for() method looks like the correct solution.
I run this code (from the docs):
import asyncio
async def eternity():
# Sleep for one hour
await asyncio.sleep(3600)
print('yay!')
async def main():
# Wait for at most 1 second
print('wait for at most 1 second...')
try:
await asyncio.wait_for(eternity(), timeout=1.0)
except TimeoutError:
print('timeout!')
asyncio.run(main())
The docs are here: https://docs.python.org/3/library/asyncio-task.html?highlight=wait_for#asyncio.wait_for
However, I get the following error:
Exception has occurred: TimeoutError
exception: no description
...basically, the TimeoutError exception is not handled as expected.
My research shows that others have struggled with errors, for example here: Handling a timeout error in Python sockets
but the fixes are either aged (not relevant for 3.10) or do not work. I also notice that the docs specify this "Changed in version 3.10: Removed the loop parameter". So i am only interested in version 3.10 and above.
So I am wondering how to get the min reproducible example working or what i have done wrong please ?
You can remove the TimeoutError so it can jump down to the print('timeout') or can use this example to output the error
except Exception as exc:
print(f'The exception: {exc!r}')
