Shift Rectangle up using Python?

Here's what I'm using to draw the rectangle

    cv2.rectangle(img,(x,y), (x+w,y+h),(0,255,255),5)

I want to move the rectangle upward by some pixels. How do I do that?

the y axis points down in 2d opencv/numpy, so you need to subtract something, to make it go up:

y -= 5
cv2.rectangle(img,(x,y), (x+w,y+h),(0,255,255),5)
