第五章:异步编程 除了顺序和并行执行模型之外,还有一个与事件编程概念一起具有基本重要性的第三个模型:异步模型。 异步任务的执行模型可以通过单一的主控制流来实现,无论是在单处理器系统还是多处理器系统中。在并发异步执行模型中,各种任务的执行在时间线上交叉,并且一切都发生在单一控制流(单线程)的作用下。一旦...

This new technology took the world by storm, but it’s complexity is still hard to compete with. First of all, there are state-level regulations, integrations with di erent services and institutions, bankAPIconnections, etc. to deal with. The second step is to conquer the hearts and the t...
You’re going to create a socket object using socket.socket(), specifying the socket type as socket.SOCK_STREAM. When you do that, the default protocol that’s used is the Transmission Control Protocol (TCP). This is a good default and probably what you want. Why should you use TCP?

Python also provides a special built-in function called complex() that lets you create complex numbers. You can use complex() as follows: Python >>> c = complex(2, 3) >>> c (2+3j) >>> type(c) <class 'complex'> You can use either method to create complex numbers. You can ...
