Test whether the python script that calls *. py can be used

Import java. io. IOException; public class JythonUtilTest {/*** @ param args */public static void main (String [] args) {String path = "E: \ PythonScript \ hello. py "; try {// execute through the pythonexecute method of the tool class *. py script, passed in the file path JythonUtil. pythonExecute (path); System. out. println ("executed successfully");} catch (IOException e) {e. printStackTrace ();}}
