New submission from Conrad <conrad...@hotmail.com>:
import asyncio
async def test():
raise Exception("Something goes wrong")
async def main():
#Un-comment either 1 of the following 3 lines
# await test() # will not call exception_handler
# await asyncio.gather(test()) # will not call exception_handler
# asyncio.create_task(test()) # will call exception_handler
await asyncio.sleep(5)
def exception_handler(loop, context):
exception = context.get("exception", None)
print("exception_handler", exception)
if __name__ == "__main__":
loop = asyncio.get_event_loop()
loop.set_exception_handler(exception_handler)
loop.run_until_complete(main())
print("Job done")
