I'm working on a simple graphics package. I've got a function show() that the user needs to call at the end of the script to actually display the points, lines and circles that have been defined in the script.
p1 = point(0, 0) l1 = line(1, 3, -4, 5) c1 = circle(-2, 3, 1) show() In each __init__() method of the point, line, and circle objects I add self to a list in a separate module, then show() uses this list to actually draw the objects. This works except: l1 = line(point(1, 3), point(-4, 5)) c1 = circle(point(-2, 3), 1) adds the references to the points used to define the objects to the render list. I only want objects that have been assigned to a variable to be rendered. (Try to ignore the function overloading.) So how can I tell if an instance of point, line or circle has actually been assigned to a variable? -- bytecolor -- http://mail.python.org/mailman/listinfo/python-list
