return (a * b)

貳、 实验要求
创建工程项目,使用Python语言实现具体的操作运算,并完成程序调试和运行,代码托管到码云。
注:在华为ECS服务器(OpenOuler系统)和物理机(Windows/Linux系统)上使用VIM、IDLE、Pycharm等工具编程实现。
參、 实验内容及结果
(1) 实验代码的使用
A. 代码1的使用

B. 代码2的使用

肆、 上传到gitee
(1) 将所写的py程序移入

(2) add与comission


(3) 推送

python真的很强大,丰富的库简单的语法降低了编程难度,但是Python 对于变量的理解与其它许多编程语言有所不同,无需定义类型的特性使得代码简洁且方便,BUT在一定程度上会混淆程序员对变量定义与赋值。
