I\'m currently writing a game project as for the game \"4 in a row\". To make the animation where the picture widget disk falls in the column, I\'ve been thinking about crea
Yes there is, it is a method of a widget named coords,
coords(tagOrId, x0, y0, x1, y1, ..., xn, yn) Queries or modifies the coordinates that define an item. If no coordinates are specified, this method returns a tuple whose elements are the coordinates of the item named by tagOrId. If coordinates are specified, then they replace the current coordinates for the named item. If tagOrIdrefers to multiple items, then the first one in the display list is used - From "Python and Tkinter Programming" by John E. Grayson
Example:
root = Tk()
calibCanvas = Canvas(root, width=800,height=800,bg='WHITE')
canvasRect = calibCanvas.create_rectangle(400,400,410,410, outline='BLUE')
print calibCanvas.coords(canvasRect)
