AttributeError: 'module' object has no attribute 'cv'

@rykov8 hello, i need your help. As you can see in the picture, my computer's version is the same with what you were supposed.It says it has no module named cv . but I do have it. I check this question by Google and StackOverflow, some says it is because the cv2.so is not in dist-packages of python. But actually my cv2.so is in it. Others say in Opencv3 the cv module is deprecated. So, in line 24 I should initialize the font like following cv2.CV_CAP_PROP_FRAME_WIDTH. i tried it but get another error like the following picture. I don't know how to fix it and beg for your help.
