## 一、安装 ##

首先需要安装jython-installer-2.7.1的jar包工具。下载地址：[https://www.jython.org/][https_www.jython.org]

## 二、注意需要默认安装 ##

## 三、使用cmd进入jython环境 ##

3.1、配置环境变量

3.2、注册环境点击运行`jython_regrtest.bat`

3.3、最后后使用命令进行转换，但是只有`jython-installer-2.2.0`版本才能使用命令进行转换，由于`jython-installer-2.7.0`的版本升级，现在直接类型配置文件或者写在`run()或者main(`)方法中才能运行。  
**引入pom.xml**

        if(param[1]+param[2]) == 0:
            reslut ="除数不能为0"
        else:
            res = param[0]/(param[1]+param[2])
            reslut ="this count: "+str(res)
        print(reslut)

        countNum([10,2,3])

    #定义一个方法
    def my_test(name, age):
        print("name: "+str(name))
        print(age)  #str()防解码出错
        return "success"
    #主程序
    #sys.argv[1]获取cmd输入的参数
    my_test(sys.argv[1], sys.argv[2])
