Yes, moving the circle changes the value of moving_circle.getCenter(). The problem is interpreting the output. The command gives <graphics.Point object at 0x0000013E0D263668>, and I don't know how to determine the x-coordinate of the center from that output. This is my problem. I can't translate the .getCenter() output to Cartesian coordinates.

Distinguish between the circle's center and the initial center point I declared. My program can output the former, but it's in a format that I don't understand: <graphics.Point object at 0x0000013E0D263668>.
As for the initial center point (I'll call it moving_circle_*initial*_center instead), it won't change at all throughout the program execution.
I need to know the x- and y-coordinates of moving_circle.getCenter() at any point in time. I can't use the center of the circle *before* it started moving, because that value is static (in other words, moving_circle_initial_center.getX() and moving_circle_initial_center.getY() never change).
