同样的我们需要安装jython，具体的步骤如下：
1. 去 http://sourceforge.net/projects/jython/ 下载最新的jython相关的jar包。
2. 下载下来的jar包其实既是使用的时候需要引入的jar包，也是安装就jython的jar包。具体安装细节参照：https://wiki.python.org/jython/InstallationInstructions#jython-2-7-0
其实直接使用： java -jar jython_installer-2.5.2.jar 就可以根据界面指导进行安装。
3. 如果我们现在想在java中调用python代码或者执行python文件，我们只需引入jypthon安装目录下的jython.jar即可。（这一点和jruby的使用方式类似）
调用的代码示例如下：
1 PythonInterpreter interpreter = new PythonInterpreter(); 2 interpreter.exec("days=('mod','Tue','Wed','Thu','Fri','Sat','Sun'); "); 3 interpreter.exec("print days[1];");
首次调用会输出很多标红的编译对应jar包的信息:

后续调用的结果如下：
