我认为这样的合作是必要的

coroutines = [asyncio.ensure_future(transfer_data(getter, sender)) for getter, sender in getter_sender_list]

您可以检查代码是否随时间异步运行

from time import time

begin = time()
loop = asyncio.get_event_loop()          
loop.run_until_complete(transfer_all())          
loop.close()                             
end = time()
print('running time: {0:.3f}sec'.format(end - begin))
