class Geometry(object):
    # Explicit attribute:
    geo_color = "green"
    # Property:
    @property 
    def color(self): 
        return self._color
    @color.setter
    def color(self, value):
        self._color = value
#
class Line(Geometry):
    def Draw(self, Point1, Point2):
        # draw line ...
        pass

line = Line()
line.geo_color = "white"
color = line.geo_color
print line.geo_color
print color
