python中的协程提供了哪些功能来改善朴素的消费者/生产者设置？
|
我已经读过一些有关协程的知识，特别是关于python的知识，而对我来说，这并不是完全显而易见的。
我已经实现了生产者/消费者模型，其基本版本如下：
#!/usr/bin/env python
class MyConsumer(object):
def __init__(self, name):
self.__name = name
def __call__(self, data):
return self.observer(data)
def observer(self, data):
print self.__name + \': \' + str(data)
class MyProducer(object):
def __init__(self):
self.__observers = []
self.__counter = 0
def add_observer(self, observer):
self.__observers.append(observer)
def run(self):
while self.__counter < 10:
for each_observer in self.__observers:
each_observer(self.__counter)
self.__counter += 1
def main():
consumer_one = MyConsumer(\'consumer one\')
consumer_two = MyConsumer(\'consumer two\')
producer = MyProducer()
producer.add_observer(consumer_one)
producer.add_observer(consumer_two)
# run
producer.run()
if __name__ == \"__main__\":
main()

嘘伪
def observer(self, data): self.odd_sample = !self.odd_sample if self.odd_sample: print str(data)while True: y = producer() print(y) y = producer() # ignore this value
