25、代码编写的最佳实践与命名规范

代码编写的最佳实践与命名规范

在软件开发过程中,编写高质量、易维护的代码是每个开发者的追求。本文将介绍一系列代码编写的最佳实践和命名规范,帮助开发者提升代码的可读性和可维护性。

通用编程原则
  1. 避免使用否定条件语句
    • 否定条件语句比肯定条件语句更难理解,因此在可能的情况下,应使用肯定条件语句。
    • 示例:
// 推荐
if (buffer.shouldCompact())
// 不推荐
if (!buffer.shouldNotCompact())
  1. 函数应只做一件事
    • 函数如果包含多个执行不同操作的部分,应该拆分成多个更小的函数,每个函数只做一件事。
    • 示例:
// 原代码
public void pay() {
    for (Employee e : employees) {
        if (e.isPayday()) {
            Money pay = e.calculatePay();
            e.deliverPay(pay);
        }
    }
}
// 重构后
public void pay() {
    for (Employ

Python编程实战 · 基础入门篇 | 变量与命名规范

简单来说,变量就是用来保存数据的名字。x = 5在 Python 中同样如此。变量x指向一个值5,我们可以使用它、修改它、再赋值给新的变量。可以这样理解:变量就像贴着标签的盒子,盒子里装着数据。你可以随时换掉盒子里的内容,只要标签还在,程序就能找到它。

Python命名规范与代码风格:写出优雅代码

代码是写给人看的,只是恰好能被机器执行。在Python社区,这句格言被奉为圭臬。 PEP 8(Python Enhancement Proposal 8)作为Python官方的代码风格指南,自2001年由Guido van Rossum等人创立以来,一直是Python开发者遵循的编码圣经[reference:0][reference:1]。

终端运行脚本报: 因为在此系统上禁止运行脚本。有关详细信息,请参阅 https:/go.microsoft.com/fw link/?LinkID=135170 中的 about_Execution_

PowerShell 执行策略是一种安全机制,用于控制哪些脚本可以在系统上运行。默认情况下,Windows 系统会设置较为严格的执行策略,以防止恶意脚本的执行。执行策略有以下几种常见级别:Restricted(限制):不允许运行任何脚本。AllSigned(全部签名):仅允许运行经过数字签名的脚本。RemoteSigned(远程签名):允许运行本地脚本,但远程下载的脚本需要数字签名。Unrestricted(无限制):允许运行所有脚本,但会警告未签名的脚本。
