Python Overview (Object-oriented, interpreted programming language)
Python（[ˈpaɪθən]）是一种面向对象、解释型计算机程序设计语言。 Python 语法简洁、清晰，具有丰富和强大的类库。 因此，Python 也是当下大数据、AI 人工智能、区块链、等的最流行开发语言。
Python 由 Guido van Rossum 于 1989 年底发明，第一个公开发行版发行于 1991 年。 Python 源代码遵循 GPL (GNU General Public License) 许可授权协议，Linux Ubuntu 默认将其集成为首选系统级维护语言。

Python 是一门跨平台的脚本语言，Python 只规定了一种语法规则。若采用不同编程语言实现 Python 语法并解释程序，就成了一种不同的 Python 解释器。
不管采用哪种编程语言实现 Python 解释器，在编写 Python 应用时的代码规范及语法规则是不变的，变化的只是底层解释器实现，即 "运行时" 的方式。
| Implementation | Underlying Language | Python Version | Explanation | Remark |
|---|---|---|---|---|
| CPython | C | 2.7.18 3.9.7 |
Classic Python, also the original Python implementation When it needs to be distinguished from other implementations, it is called CPython; Or called Python implemented in C language |
This is the most commonly used version of Python |
| MicroPython | C | 3.4.4 | Mainly used for IoT MCU (micro control unit, also known as single chip microcomputer) | Made a lot of simplifications to Python |
| PyPy | Python | 2.7.18 3.7.9 | Python implementation written in Python language | Officially claimed that the average speed is 4.2 times that of CPython |
| Python for .NET | C | Manage .NET applications and call .NET libraries | This implementation is actually based on CPython | |
| IronPython | .NET | 2.7.18 3.4.4 | Python implementation for .NET and ECMA CLI |
IronPython can directly call the .NET platform function library Compile Python applications into .NET programs |
| Jython | Java | 2.7.18 | Python implemented in Java language | Jython can directly call the Java function library |
| ZhPy | Also known as Zhou Mang, Python implementation that supports of writing applications using Traditional/Simplified Chinese sentences |
Python 常被称为胶水语言，能把用其他语言编写的各模块 (尤其是 C/C++) 轻松地联结在一起。常见情形是，用 Python 快速生成程序原型 (有时甚至是程序最终界面)，然后对其中有特别要求的部分，用更合适的语言改写。
譬如：3D 游戏中的图形渲染模块，性能要求特别高，就可用 C/C++ 重写，而后封装为 Python 可调用的扩展类库。需要注意的是，在使用扩展类库时可能需要考虑平台问题，某些扩展类库可能不提供跨平台实现。
