python代碼轉jar包

一、安裝

首先需要安裝jython-installer-2.7.1的jar包工具。下載地址：https://www.jython.org/

二、注意需要默認安裝

三、使用cmd進入jython環境

3.1、配置環境變量

3.2、註冊環境點擊運行jython_regrtest.bat

3.3、最後後使用命令進行轉換，但是隻有jython-installer-2.2.0版本才能使用命令進行轉換，由於jython-installer-2.7.0的版本升級，現在直接類型配置文件或者寫在run()或者main()方法中才能運行。
引入pom.xml

    if(param[1]+param[2]) == 0:
        reslut ="除數不能爲0"
    else:

    print(reslut)

if __name__=="__main__":
    countNum([10,2,3])

#定義一個方法

    print("name: "+str(name))
    print(age)  #str()防解碼出錯

#主程序
#sys.argv[1]獲取cmd輸入的參數
