Running on top of the asyncio event loopΒΆ

Note

New in prompt_toolkit 3.0. (In prompt_toolkit 2.0 this was possible using a work-around).

Prompt_toolkit 3.0 uses asyncio natively. Calling Application.run() will automatically run the asyncio event loop.

If however you want to run a prompt_toolkit Application within an asyncio environment, you have to call the run_async method, like this:

from prompt_toolkit.application import Application

async def main():
    # Define application.
    application = Application(
        ...
    )

    result = await application.run_async()
    print(result)

asyncio.get_event_loop().run_until_complete(main())
