Serial data Manipulation

hi, i have a big probelm, im using a two potentiometre and i want to send the value from the arduino to python with Serial Transmission and then manipulate the analog Value, my problem just the manipulation in the python??!!

Many manipulations possible are documented here https://www.python.org/

Normally I do not manipulate in the Python. ;)

This Python - Arduino demo may be helpful.
