The generally-accepted solution for this task is to set an Event, rather than
just returning a Boolean:
def move_to(dest, done_event):
...
done_event.set()
async def main():
dest = ...
done_event = asyncio.Event()
create_task(move_to(dest, done_event))
await done_event
print('Arrived!')
And naturally you could wrap an existing function that returns a Boolean:
async def move_to(dest) -> bool:
...
async def set_if_success(event, awaitable):
result = await awaitable
if result:
event.set()
async def main():
dest = ...
done_event = asyncio.Event()
create_task(set_if_success(done_event, move_to(dest)))
await done_event
print('Arrived!')
