Sending serial or i2c commands from python

Hello community !

Is it best to use the raspberry to communicate with the nyboard using i2c, or serial ?

And what do I need to import to my behaivor script to send skill commands to the nyboard?

If using serial, would it be as simple as:

 "from ardSerial import *"

then define serial port:

"ser = serial.Serial ..//.."

and then calling:

"serialWriteByte(["ksleep"])"

Or am I missing something here ?

Hope you can help me Sending commands to nybble with python.

Thank you.
