'Why the loop is infinite?

When I use this code, it runs infinite loop, and the image which I want to show it ,does not respond and appear as a gray picture

    h,w=Img.size
    for x in range(h):
        for y in range (w):
            r, g, b = Img.getpixel((x, y))
            a = (r, g, b)
            print (a)
    cv2.imshow("Mark Zukerberg", Img)

python

The loop isn't actually infinite, it is just a very long, large, process, so it will take a while to finish. If you were to have it print y and/or x every time it iterates, you can see it is incrementing, just more slowly then wanted. I would recommend using a compiled language, such as C++, Java, or Go for loops this large, as they will run faster.

print actually takes more resources than you would expect, so that might be the issue. Try removing the print function.
