结果:

其他两种 调用方法:

a) 直接执行Python脚本代码

PythonInterpreter interpreter = new PythonInterpreter();  
interpreter.exec("days=(&#39;mod&#39;,&#39;Tue&#39;,&#39;Wed&#39;,&#39;Thu&#39;,&#39;Fri&#39;,&#39;Sat&#39;,&#39;Sun&#39;); ");   ///执行python脚本

b)使用Runtime.getRuntime()执行脚本文件

Process proc = Runtime.getRuntime().exec("python  D:\\demo.py");  
proc.waitFor();
Copy after login
