Collections attribute deprecation in version > 3.8

Hi, @rcomer.

Could you please clarify, what is the proper way to change the following code (which was removing contours from plot):

            if isinstance(contour, ContourSet):
                for lineset in contour.collections:
                    lineset.remove()

The problem for me is that if I try to replace collection with get_paths, then remove method does not work on path.
If I try removing path via del (for example, as follows):

            for k, path in enumerate(contour.get_paths()):
                 del contour.get_paths()[k]

then the contour to be removed remains in the image.

Many thanks in advance
