The other two methods of invocation are:

A) Execute Python script code directly

Pythoninterpreter interpreter = new Pythoninterpreter ();  Interpreter.exec ("days=" (' MoD ', ' Tue ', ' Wed ', ' Thu ', ' Fri ', ' Sat ', ' Sun ')   ; Execute Python Script

b) Execute script file using Runtime.getruntime ()

Process proc = Runtime.getruntime (). EXEC ("Python  d:\\demo.py");  Proc.waitfor ();
