在我们这个技术驱动的社会中,小工具和硬件只是硬币更明显的一面。在这一章中,我们将讨论编程的基础知识。我们还将看看数字系统的可见部分:硬件。 到底什么是编程? 基本上,编程是告诉数字设备,比如你的个人电脑,做什么的行为。我们键入由编程语言定义的命令列表,以便发生有用或有趣的事件。正确编程的计算机运行着世界...
由于NumPy 提供了全面且有文档的 C API,因此将数据传递给用低级语言编写的外部库,以及让外部库将数据作为 NumPy 数组返回给 Python 是很简单的。这个特性使 Python 成为封装传统 C、C++或 FORTRAN 代码库并为其提供动态和可访问接口的首选语言。 虽然NumPy 本身并不提供建模或科学功能,但了解 NumPy 数组和面向数组...

So, that’s the question we’re trying to ask today: “What’s the maximum integer value we can represent on a certain machine?” 2. Problem Explanation Well, there isn’t a unique answer to this question since there are many factors that influence the answer. The main ones are: Platfo...
