Random numbers in PyBee VOC

Question

I'm trying to generate random numbers in Python code running on the JVM with PyBee's VOC transpiler. For now, it looks like the Python random module isn't included, so how can I generate random numbers?

Here's the code I tried to transpile:

from random import randrange

print(randrange(5))

And here's the error when I run the class file in Java:

Exception in thread "main" java.lang.ClassCastException: org.python.java.Module (in module: Unnamed Module) cannot be cast to org.python.Callable (in module: Unnamed Module)
    at python.example.module$import(example.py:3)
    at python.example.main(example.py)

It looks like my Python code can access all the standard Java libraries, so I just have to emulate the random module with Java.

from java.util import Random

r = Random()
randrange = r.nextInt

print(randrange(5))

If I want to test my code on Python before deploying to the JVM or Android, I can pass in the randrange() function as a parameter.
