机器学习越来越多应用到飞行器、机器人等领域，其目的是利用计算机实现类似人类的智能，从而实现装备的智能化与无人化

## hellopython > 学习目的：掌握Python的使用以及文件读取、画图等实际操作 > > 课程学习内容：Python语法、Python画图、文件I/O操作 > > 参考：[Python简介及发展历史(学习小助手)](https://zhuanlan.zhihu.com/p/169624095) > > [matplotlib](https://matplotlib.org/stable/gallery/index.html) ### 课程介绍 <p align="center"> <img src="./images/pythonLogo3.jpg"/> </p> #### 一、Python的起源与发展 Python，读作`['paɪθɑn]`，翻译成汉语是蟒蛇的意思，并且Python的logo也是两条缠绕在一起蟒蛇的样子，然而Python语言和蟒蛇实际上并没有一毛钱关系。Python的口号是："人生苦短，我用Python!"。Python语言是由荷兰程序员**Guido van Rossum**，江湖人称“龟叔”，独立开发完成初版的 。1989年圣诞节期间，在阿姆斯特丹，为了打发圣诞节的无趣，决心开发一个新的脚本解释语言，作为ABC语言的一种继承，然后完成了python语言初始版本的开发（龟叔很硬核）。之所以选中Python作为该编程语言的名字，是因为他是一个叫**Monty Python**喜剧团体的粉丝，其本意并不是想选条蟒蛇。Python第一个公开发行版发行于1991年，所以这年被当作Python的诞生年。Python 源代码遵循 GPL(GNU General Public License)协议，这是一个开源的协议，也就是说你可以免费使用和传播它，而不用担心版权的问题。 <p align="center"> <img src="./images/Pythonfather2.jpeg"/> </p> 1.
