Java调用python的方法（jython）

PythonInterpreter interpreter = new PythonInterpreter(); 
interpreter.exec("days=('mod','Tue','Wed','Thu','Fri','Sat','Sun'); "); 
interpreter.exec("print days;"); 

PythonInterpreter interpreter = new PythonInterpreter();  
 interpreter.execfile("script.py");  

def pluser(a,b): 
  # print "the result of pluser is %d" % (a+b) 
  return a+b 

PythonInterpreter interpreter = new PythonInterpreter(); 
    interpreter.execfile("F:\\machine learning\\machinelearninginaction\\Ch02\\test.py"); 
    PyFunction function = (PyFunction)interpreter.get("pluser",PyFunction.class); 
    PyObject o = function.__call__(new PyInteger(8),new PyInteger(23));
