Project description

PyPI python versions license


Transform your python code from old syntax with yield from to use async/await (PEP 492).


$ pip install yield2await
$ yield2await <path> [-i <ignore-path>]


def handler(request):
    session = yield from get_session(request)
    session['last_visit'] = time.time()
    with (yield from self.dbengine) as conn:
        ret = yield from conn.execute(query)
        user = yield from ret.fetchone()
    return web.Response(body=b'OK')


async def handler(request):
    session = await get_session(request)
    session['last_visit'] = time.time()
    async with self.dbengine as conn:
        ret = await conn.execute(query)
        user = await ret.fetchone()
    return web.Response(body=b'OK')


Feel free to contribute. Just do RP.


This is a very alpha, check the changes manually before commit.
