Python语言

 ‌  语法简洁易学‌：Python的语法设计接近自然语言，强调代码可读性，使用强制缩进而非大括号来定义代码块，这使得它非常适合编程初学者入门。‌‌

   支持多编程范式‌：Python完全支持‌面向对象编程‌，同时也支持‌过程式‌和‌函数式编程‌范式，开发者可以根据需求灵活选择编程风格。‌‌

   开源且跨平台‌：Python是‌FLOSS（自由/开放源码软件）‌，使用者可以自由地发布、阅读和修改其源代码。由于其开源本质，它已被移植到几乎所有主流操作系统上，包括Windows、Linux、macOS等，同一代码无需修改即可在不同平台运行。‌‌

   动态类型与解释执行‌：Python是‌动态类型语言‌，变量类型在运行时自动推断，无需显式声明。同时，它是‌解释型语言‌，程序无需提前编译为机器码，通过解释器逐行执行，这使得开发和调试过程更加快捷。‌‌‌
