How to use the aioitertools.itertools.permutations function in aioitertools

itr: AnyIterable[T], r: Optional[int] = None
) -> AsyncIterator[Tuple[T, ...]]:
    """
    Yield r length permutations of elements in the iterable.

    Simple wrapper around itertools.combinations for asyncio.
    This will consume the entire iterable before yielding values.

    Example:

        async for value in permutations(range(3)):
            ...  # (0, 1, 2), (0, 2, 1), (1, 0, 2), ...

    """
    pool: List[T] = await list(itr)
    for value in itertools.permutations(pool, r):
        yield value
