Every shape type, except the "Null" type contains points at some level for, example vertices in a polygon. Floats required. You need to tell your system where to search for QGIS libraries and appropriate Python modules if they are not in a well-known location - otherwise Python will complain: >>>importqgis.core ImportError: No module named qgis.core This can be fixed by setting the PYTHONPATHenvironment variable. Only a few less-common functions are accessible only via ox.module_name.function_name(). Assume the Python installation direcotry is C:\Python27.

In this case, the PYTHONPATH variable has not been set up correctly, and you will have to check the commands you entered earlier to set this environment variable, and possibly modify it to allow for a nonstandard location of the QGIS libraries.
