在python里从协程返回一个值的示例

import asyncio
 
async def coroutine():
  print('in coroutine')
  return 'result'
 
event_loop = asyncio.get_event_loop()
try:
  return_value = event_loop.run_until_complete(
    coroutine()
  )
  print('it returned: {!r}'.format(return_value))
finally:
  event_loop.close()

in coroutine
it returned: 'result'
