I need to make a picture and store it as a document using python. 

I anticipate that the output should be a picture with shading squares of black or white, and the image should have 6x6 squares of random white or dark color blocks.

Try the following code, to solve the problem:

#Import all libraries we will use

import random

import numpy as np

import cv2

#let's create a 6 x 6 matrix with all pixels in black color

img = np.zeros((6,6,3),np.uint8)

#let's use "for" cycle to change colorspace of pixel in a random way

for x in range(6):

    for y in range(6):

        #We use "0" for black color (do nothing) and "1" for white color (change pixel value to [255,255,255])

        value = random.randint(0,1)

        if value == 1:

            img[x,y] = [255,255,255]

#save our image as a "png" image
