虚拟环境(Virtual Environment)是 Python 中用于隔离项目依赖和运行环境的工具。它允许你在同一台计算机上同时管理多个项目,每个项目都有自己独立的 Python 解释器和第三方库,互相之间不会相互干扰。使用虚拟环境的好处包括:隔离依赖:每个项目可以有自己的依赖库,不同项目之间的依赖冲突不会发生。 简化部署:可以将项目的...
环境配置是配置你的计算机环境,以便你写代码的过程。这包括安装任何必要的工具,配置它们,以及处理安装过程中的任何问题。没有一键配置这种傻瓜式操作过程,因为每个人都有一台不同的计算机,不同的操作系统、不同操作系统版本 、不同的 Python 解释器版本。尽管如此,本章描述了一些基本概念,帮助您使用命令行、环境变量和...

To get the desired behavior you can pass in the loop variable as a named variable to the function. Why does this work? Because this will define the variable inside the function's scope. It will no longer go to the surrounding (global) scope to look up the variables value but will ...
