This +presents a practical problem: When in an environment where the event +loop is already running it's impossible to run tasks and wait for the +result. Trying to do so will give the error "RuntimeError: This event +loop is already running". + +The issue pops up in various environments, such as web servers, GUI +applications and in Jupyter notebooks. + +This module patches asyncio to allow nested use of asyncio.run and +loop.run_until_complete. |
