generator: a function that produces a sequence of values for use in iteration
-
countdown(10)below returns a generator object -
c.next()will execute statements until it reaches ayieldstatement -
c.close()will shutdown the generator, which is no longer used
-
def receiver():
while True:
n = (yield)
print("Got %s", % n)-
coroutine: a function which uses yield for its value
- more like a consumer (opposite of generator) but the execution behavior is quite similar to generator

- decorated with
@asyncio.coroutine - two types of coroutines:
- callee: the function definition itself (
iscoroutinefunction()) - call instance: the object objtained by calling a coroutine function (
iscoroutine())
- callee: the function definition itself (
- inside coroutine body, it can do:
-
result = yield from future: suspends this coroutine until the future is done -
result = yield from coroutine: wait for another coroutine to produce a result (or raise exception); it must be call to another "coroutine" return expressionraise exception- yield from == await
