Check if a newly created canvas_image is overlapping a previously made canvas_image Python Tkinter

I want to get an output when plansquare is overlapping a new plansquare (they are being created every millisecond), but I'm not sure how to do it. So far, I check the coordinates of the new plansquare, and what I want to happen is for it to check if it is touching any other plansquare, and if so it will execute canvas.delete(plansquare).

def planwallfunc(event):
    press = True
    print(press)
    x, y = event.x, event.y
    def create_rectangles():
        global x
        global y
        global plansquare
        x, y = event.x, event.y
        plansquare = canvas.create_image(x, y, image=planwall)
        plansquarecoords = canvas.coords(plansquare)
        if canvas.find_overlapping(plansquarecoords):
            canvas.delete(plansquare)
        else:
            plansquare = canvas.create_image(x, y, image=planwall)
    root.after(1, create_rectangles)

My error is TypeError: find_overlapping() missing 3 required positional arguments: 'y1', 'x2', and 'y2' which means it is interpreting plansquarecoordsas x1. I instead want it to interpret it as all 4 - x1, y1, x2, y2 but I'm not sure what to do.

Anyone know?

The method requires four positional arguments but you're giving it one argument with four values.

The simplest solution is to use the * operator to expand the list of four coordinates into four separate parameters:

canvas.find_overlapping(*plansquarecoords)
