Python协程：从yield/send到async/await

这个文章理好了脉落。 http://python.jobbole.com/86069/ 我练习了一番，感受好了很多。。。 Python由于众所周知的GIL的原因，导致其线程无法发挥多核的并行计算能力（当然，后来有了multiprocessing，可以实现多进程并行），显得比较鸡肋。既然在GIL之下...

理解Python的协程机制-Yield

根据PEP-0342 Coroutines via Enhanced Generators，原来仅仅用于生成器的yield关键字被扩展，成为Python协程实现的一部分。而之所以使用协程，主要是出于性能的考虑：一个活跃的Python线程大约占据8MB内存，而一个活跃线程只使用1KB不到内存。对于IO...
