Jython not getting the python method. Why?

Question

I'm really new to Jython and I have a code like this:

 interpreter.exec("import sys\nsys.path.append('my-path')\nimport hello");
 PyObject someFunc = interpreter.get("getDriverObect");

someFunc is always null! Here is the corresponding code for python:

from selenium import webdriver
def getDriverObect():
 c = webdriver.Safari()
 return c

I tried the following the combination as well, nothing is working out:

PyObject someFunc = interpreter.get("hello.getDriverObect");
PyObject someFunc = interpreter.get("hello.getDriverObect()");
PyObject someFunc = interpreter.get("getDriverObect()");

Where I'm making mistake?

Answer 1

The function object is not available via interpreter.get("getDriverObject") unless you use from hello import getDriverObject.

Simplified hello.py:

def getDriverObject():
 return "TEST"

Java code:

interpreter.exec("from hello import getDriverObject");
PyObject func = interpreter.get("getDriverObject");
System.out.println(func);
System.out.println(func.__call__());

Output from the above:

<function getDriverObject at 0x2>
TEST

You could also do it like this:

interpreter.exec("import hello");
PyObject module = interpreter.get("hello");
PyObject func = module.__getattr__("getDriverObject");
