loop = asyncio.get_event_loop() call fails

Hi there; When I try to call blocking normalize function. Call fails with

RuntimeError: There is no current event loop in thread 'Thread-7'.

@orhanbalci Did you find a solution?

EDIT: #4 contains the solution!

I was using this library from a django project. Django has a utility function which converts an async function into a sync one. By using async_to_sync function I managed to call async normalize function.

def normalize_email(email: str) -> str:

    async def normalize_inner(email: str):
        normalizer = Normalizer()
        return await normalizer.normalize(email)

    normalized_email = email
    try:
        sync_normalize = async_to_sync(normalize_inner)
        normalisation_result = sync_normalize(email)
        if normalisation_result is not None:
            normalized_email = normalisation_result.normalized_address
    except BaseException:
        logger.exception("Error occured when normalizing %s ", email)

    return normalized_email`

Using it as a decorator is a lot cleaner:

from asgiref.sync import async_to_sync
from email_normalize import Normalizer, Result


@async_to_sync
async def normalize(email: str) -> Result:
    normalizer = Normalizer()
    return await normalizer.normalize(email)
