The Zen of Python是Python语言的指导原则,遵循这些基本原则,你就可以像个Pythonista一样编程。具体内容你可以在Python命令行输入import this看到: The Zen of Python, by Tim Peters Beautiful is better than ugly. # 优美胜于丑陋(Python以编写优美的代码为目标) Explicit is better than implicit. # 明了胜于...
Now that we know about strings and arrays in Python, we simply combine both concepts to create and array of strings. For example to store different pets. To declare and initialize an array of strings in Python, you could use: # Create an array with pets my_pets =['Dog','Cat','Bunny...
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...

The array module in Python allows you to create and initialize an array and for that, you first need to import it first. Now, let’s look at the example of declaring an array in Python. To create an array, the basic syntax is: Python 1 2 3 from array import array array_name =...

It’ll take care of creating a README.md file and a .gitignore file, and then it’ll run a few commands to create a virtual environment, initialize a git repository, and perform your first commit. It’s even cross-platform, opting to use pathlib to create the files and folders, ...
NumPy数组也可以使用逻辑索引进行索引,但这实际上意味着什么? Just as we can have an array of numbers, we can have an array consisting of true and false, which are two Boolean elements. 正如我们可以有一个数字数组一样,我们也可以有一个由true和false组成的数 ...
