同樣的我們需要安裝jython，具體的步驟如下：

1. 去?http://sourceforge.net/projects/jython/?下載最新的jython相關(guān)的jar包。

2. 下載下來(lái)的jar包其實(shí)既是使用的時(shí)候需要引入的jar包，也是安裝就jython的jar包。具體安裝細(xì)節(jié)參照：https://wiki.python.org/jython/InstallationInstructions#jython-2-7-0

其實(shí)直接使用： java -jar?jython_installer-2.5.2.jar 就可以根據(jù)界面指導(dǎo)進(jìn)行安裝。

3. 如果我們現(xiàn)在想在java中調(diào)用python代碼或者執(zhí)行python文件，我們只需引入jypthon安裝目錄下的jython.jar即可。（這一點(diǎn)和jruby的使用方式類似）

?

調(diào)用的代碼示例如下：

1 PythonInterpreter interpreter = new PythonInterpreter(); 2 interpreter.exec("days=('mod','Tue','Wed','Thu','Fri','Sat','Sun'); "); 3 interpreter.exec("print days[1];"); JavaCallPython

首次調(diào)用會(huì)輸出很多標(biāo)紅的編譯對(duì)應(yīng)jar包的信息:

后續(xù)調(diào)用的結(jié)果如下：
