Multiple returns from a python function

[Preetip]

How do I handle a Python function that returns multiple lists

Python script:
display():
a = [ 'a','b','abc']
b = [ 1 , 2 , 3]
return (a,b)


In the c function calling the above python function:

pValue,pValue1 = PyObject_CallObject(pFunc, pArgs);


But then I cannot use the objects to extract the list values.
What am I doing wrong ?
