   Python version (produces same sequence of output values):   
      
       def test(v) :   
           print("B1", v)   
           v = yield 123   
           print("B2", v)   
           v = yield 456   
           print("B3", v)   
           return 789   
       #end test   
      
       try :   
           print("A1")   
           coro = test("ABC")   
           v = coro.send(None)   
           print("A2", v)   
           v = coro.send("DEF")   
           print("A3", v)   
           v = coro.send("GHI")   
       except StopIteration as ret :   
           print("A4", ret.value)   
       #end try   
      
   Note this doesn’t even need a coroutine function (async def); a simple   
   generator will do.
