Im new to Python and I need to transform some .iff Data to .shp, .shx, and .dbf data. I use the Code below in combination with the pyShape package from Joel Lawhead. And I get the Error:"... line 157, in if not w.shx.closed : w.shx.close() AttributeError: 'NoneType' object has no attribute 'closed'". This seems like a simple Error which might not be to complicated to solve but for me its hard. Maybe someone can help me.
Best regards Vestus
