create a blank image and fill it with random colors in python

Write a C program for the image attached. Thank you

Create a python program that will help user find a solution to any solvable Sudoku puzzle. You can simply start with writing text code which uses backtracking algorithm. What backtracking algorithm will do is that it will simply revert back to previous step if the solution found in current running step cannot solve the Sudoku.

Use python code with "def drawItem(img,item,row,col):" but without using cv2,PIL or numpy drawItem(canvas, item, row, col) - Modify canvas by drawing the non-white pixels of the item (intended to be the image of a word) onto canvas. Row and col represent the top left pixel of canvas where the item (the item's top left 0,0 pixel) should be placed. Canvas and item are 2D images of RGB pixels. This function should assume that the canvas image is large enough to contain the item img in the row col indicated; row and col do NOT need to be validated.
