Most of the output feature types will be the same as input (input polygons remain polygons; input lines remain lines). If the input features are of type multipoint, the output feature class will be type point. To reconstruct multipart features from singlepart features based on a common field value, such as ORIG_FID, use the Dissolve tool.arcpy.AddField_management(*(new_shapefile,) + field) Here's what's going on: the AddField_management method is used to add two fields to the shapefile's attribute class.
