How can you calculate where the middle of the screen is using math in python-CodePudding

I must've skipped school that day because I cannot remember how to calculate the middle of a square.

There are a few different ways to calculate the middle of a square using Python. One way is to find the average of the x and y coordinates of the square's four corners. Another way is to find the point that is equidistant from all four corners of the square.

# method-1
def square_middle(square):
    x1, y1, x2, y2 = square
    return ((x1   x2) / 2, (y1   y2) / 2)

# method-2    
def square_middle(square):
    x1, y1, x2, y2 = square
    cx = (x1   x2) / 2
    cy = (y1   y2) / 2
    return (cx, cy)

frameworks usually report the size of a screen with 2 values or a touple of 2. For example, this is how pyautogui reports it:

print(pyautogui.size())
Size(width=1728, height=1117)

And this is how that framework gets the center for every coordinates tuple: https://github.com/asweigart/pyscreeze/blob/master/pyscreeze/__init__.py#L579 So you can safely use the example above to get the center of any object on screen, even the screen itself.
