Python并发-阿里云

1_python高阶_线程—多任务（并发、并行）一、多任务概念什么叫“多任务”呢？简单地说，就是操作系统可以同时运行多个任务。打个比方，你一边在用浏览器上网，一边在听MP3，一边在用Word赶作业，这就是多任务，至少同时有3个任务正在运行。还有很多任务悄悄地在后台同时运行着，只是桌面上没有显示而已。现在，多核CPU已经非常普及了，但是，即使过去的...

干货：深入浅出讲解Python并发编程（四）五、协程协程，又叫微线程或者纤程。它是比线程更为细小的线程，微线程的名字由此得来。只支持python 3.4以上的版本，不过建议使用python 3.6版本，因为我的代码都是跑在3.6上的，出错找都找不见报错原因优点：使用高并发、高扩展、低性能的；一个CPU支持上万的协程都不是问题。所以很适合用于高...

干货：深入浅出讲解Python并发编程（三） 6.4 队列在线程中队列的方法有三种QueueLifoQueuePriorityQueue上述三种方法里面，Queue的方法在进程并发中已经详细做了介绍，这里就不赘述了，而后边的LifoQueue和PriorityQueue的对象属性和Queue是一样的，他们之间都是通用的，像什么qsize()、e...

干货：深入浅出讲解Python并发编程（二） 8. JoinableQueue查看官方文档可以看到，除了前边提到的使用Queue来处理队列，这里还有JoinableQueue，其实JoinableQueue就像是一个Queue对象，但是队列允许项目的消费者来通知生产者已经成功处理，通知进程是通过共享的信号和条件。class multiproce...

干货：深入浅出讲解Python并发编程（一） Python并发编程本文比较长，绕的也比较快，需要慢慢跟着敲代码并亲自运行一遍，并发编程本身来说就是编程里面最为抽象的概念，单纯的理论确实很枯燥，但这是基础，基础不牢，地洞山摇，在概念这节里面还需要好好的品味一番。注意：看本文需要Python基础，以下所有代......
