I don't really understand the question but it sounds like you might
want a class variable:
import smbus
class I2CDevice
bus = smbus.SMBus(1)
def __init__ (self): ...
This puts the "bus" object into the I2CDevice class itself. It is
created when the I2CDevice class is defined. Methods wanting to access
it can then say
do_something_with(I2CDevice.bus)
is that what you wanted?
