[Tutor] question about __init__ in a class

Hello there all.
i have a class that i need to load some class variables depending on what is
passed to the class, it would either be set up using one variable or
another. The values for the class variables would be loaded from a database.
But how it is looked up depends on how its called. Like this:

class Sensor_Object(object):
    def __init__(self, id, monitor):
        if id:
           self.id = id
           load values from the database
           value1 = somevalue
           value2 = someOthervalue
           self.monitor = monitor
           get some values from database
           value1 = somevalue
           value2 = someothervalue

now i could call it like this:

new_monitor = sensor.Sensor('', 'XJ191')
new_monitor = sensor.Sensor('3433', '')
to load based on the other variable.

i think that this would work, but i was thinking that there must be a
cleaner way to do it.
any suggestions ?
