Hi,
I'm 6 months into learning python and haven't been able to find a way
to do this, so I hope you don't mind a basic question.
I'd like to use the polygons contour makes but I can't figure out how
to get them from ContourSet. Any examples or links to helpful
information would be excellent.
Thanks,
Phil

Attached is an example of how to extract the polygons from a ContourSet.

They are buried. Each contour set has a list of collections, and
each of those collections has a set of paths, and each of those paths has a vertices attribute for its corresponding polygon. In the following we will pick out the first path of the first collection.
cs = contour(rand(6,6))
c = cs.collections[0]
p = c.get_paths()[0]
v = p.vertices
lev = cs.levels[0]
The levels attribute is a list of levels corresponding to the list of collections: one collection per level.
