aw man, try this instead:

cv2.namedWindow("lll")
cap = cv2.VideoCapture(0)
while( cap.isOpened() ) :
    ret,img = cap.read()
    cv2.imshow("lll",img)
    k = cv2.waitKey(10)
    if k == 27:
        break

@jeevitha, and what keeps you from doing such a straightforward thing ?

here, you create an instance of VideoCapture:

capture = cv2.VideoCapture(0)

then you'd want to use that instance ( not the class! )

ret,frame = capture.read()
// go on processing frame
