一.什么是python

Python由荷兰数学和计算机科学研究学会的吉多·范罗苏姆于1990年代初设计，作为一门叫做ABC语言的替代品。 Python提供了高效的高级数据结构，还能简单有效地面向对象编程。Python语法和动态类型，以及解释型语言的本质，使它成为多数平台上写脚本和快速开发应用的编程语言， [ 随着版本的不断更新和语言新功能的添加，逐渐被用于独立的、大型项目的开发。

Python解释器易于扩展，可以使用C语言或C++（或者其他可以通过C调用的语言）扩展新的功能和数据类型。Python也可用于可定制化软件中的扩展程序语言。Python丰富的标准库，提供了适用于各个主要系统平台的源码或机器码
