toasync

Convert sync function to async function and start at same time

from time import sleep, time
import asyncio
from toasync import async_


@async_
def func(name, i=1):
    print('Start function {}'.format(name))
    sleep(1)
    print('Done function {}'.format(name))


if __name__ == '__main__':
    coroutine = asyncio.gather(
        func()('1'),
        func()('2'),
        func()('3'),
    )
    start_time = time()
    asyncio.get_event_loop().run_until_complete(coroutine)
    print('Process take {} sencond'.format(time-start_time))

then

Start function 1
Start function 2
Start function 3
Done function 2
Done function 1
Done function 3
Process take 1.007418155670166 sencond

If run function as synchronous, you can call delay method

from time import sleep
from toasync import async_


@async_
def func(name, i=1):
    print('Start function {}'.format(name))
    sleep(1)
    print('Done function {}'.format(name))


if __name__ == '__main__':
    func().delay('1')
    func().delay('2')
    func().delay('3')

then

Start function 1
Done function 1
Start function 2
Done function 2
Start function 3
Done function 3
