    rectImg = img[10:20, 10:20]

but when I draw a line on it ,I find the line appear both on img and the rectImage,so , how can I get this done?

The first answer is correct but you say that you are using cv2 which inherently uses numpy arrays. So, to make a complete different copy of say "myImage":

newImage = myImage.copy()

The above is enough. No need to import numpy.
