[BangPypers] About code

[narayan naik]

Hi,

import numpy as np
import cv2
img=cv2.imread('4.jpg',0)
cv2.imshow('image',img)
k=cv2.waitKey(0)
if k == 27:
    cv2.destroyAllWindows()
    #cv2.destroyWindow('image')
elif k == ord('S'):
    cv2.imwrite('image.png',img)
    cv2.destroyAllWindows()

when I run this code,it is not possible to close the image window by
pressing esc key,and if going to close by using mouse the window will hang.
