Transform your python code to use async/await (PEP 492)

Project description

![python versions](

# yield2await

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

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

### Before
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')

### After
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')

### Contribution
Feel free to contribute. Just do RP.

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