cant find ReleaseCapture in opencv while using python?

I am trying to release a cam capture which has been acquired by the API call

    camera = cv.CaptureFromCAM(-1) 

How can I release it. There is a function named "ReleaseCapture" but it has no python bindin开发者_如何学编程g.

Can anybody suggest any alternative?

Thanks a lot

I found a similar answered question here

capture = cv.CaptureFromCAM(0)
frame = cv.QueryFrame(capture)

#some code ...

del(capture)

be carefull of using frame or another image captured from cam after deleting capture
