How do I send 2 columns as arrays to Python

Gereetings,I am trying to send two arrays from IDEAScript to Python. I know how to do it with 1 array:
In ISS: Client.RunPythonEx "Macros.ILB\PythonTest.py", array1
In Python: arguments = sys.argv[1] but I don't know how to do it with 2 arrays. How can I send 2 arrays to 1 script?
Any assistance or guidance in resolving this issue would be greatly appreciated.
Thank you.
