I found the solution, it's been emailed me from Jeff Emanuel

The complete code follows:

import java.io.*;
import java.util.*;
import java.text.*;

import org.python.util .PythonInterpre ter;
import org.python.core .*;

public class Calculate {
public static void main(String[] args){
PythonInterpret er interp = new PythonInterpret er();
interp.execfile ("script1.py ");
PyFunction func = (PyFunction)int erp.get("calcul ate",PyFunction .class);
SimpleDateForma t sdf = new SimpleDateForma t("dd/MM/yyyy hh.mm.ss");
System.out.prin tln("======[" + sdf.format(new Date()) + "]===========");
for (int i=1 ; i<10000 ; ++i) {
// Assuming calculate takes a float argument.
func.__call__(n ew PyFloat(i));
//interp.eval("ca lculate(" + i + ")");
}
System.out.prin tln("======[" + sdf.format(new Date()) + "]===========");
}
}
