django - how to convert python list[a,b,c,d] to [a:b, c:d] format -

how convert python list [a:b, c:d] format?

this format used in cropping of images in python-opencv.

suppose have cropping dimensions of image in list cropdim don't know how create opencv acceptable format image[a:b, c:d].

import cv2 def crop(cropdim): bimage = cv2.imread("nor.jpg") cropped = bimage[a:b, c:d] cv2.imwrite('nor-crop.jpg', cropped)

first of let's terminology straight - that's not python list, it's array 2 dimensions. you're trying piece on it.

cropped = bimage[cropdim[0]:cropdim[1], cropdim[2]:cropdim[3]]

python django opencv image-processing
