I have a similar problem when reading shapefile points which used NaNs to
segment the points into separate polygons - either holes within polygons, or
two polygons associated with the same record. Using Matlab's shaperead, the
break between polygons X coordinate looks like
... -157.1686 -157.1685 NaN -157.4838 -157.4892 ...
but using shapefile.py the same coordinates looks like
... -157.1686, -157.1685, -157.4838, -157.4892, ...
with no indication that there should be a break between the two polygons.
I'm running Matlab 7.9.0.529 (R2009b) on Windows 7, and Python 2.7.1
(r271:86832, Mar 7 2012, 20:54:07) with [GCC 4.1.2 20080704 (Red Hat
4.1.2-46)] on an Intel Linux box (MACHTYPE=x86_64-redhat-linux-gnu). The
version of shapefile.py is "date: 20110927,
version: 1.1.4"

I am also having issues with this.
I am trying to extract the polygon points and save them within MySQL using
Polygon Functions.
However I am unable to detect which polygons are inclusive and which are
exclusive.

Well, the support is ALMOST there.
pyshp now implements __geo_interface__
(https://gist.github.com/sgillies/2217756) support? shape. "MultiPolygon"
(http://wiki.openstreetmap.org/wiki/Relation:multipolygon) is supported, just
without polygon roles (inner/outer), which is the problem. I tried to quickly
glance how to read the inner/outer multipolygon part type here
(http://www.esri.com/library/whitepapers/pdfs/shapefile.pdf) but didn't succeed.
